I am a simple man, I see Simple Sapling Games release a video I watch
nice :] thanks g
Where were you 2 months ago when i needed to know how to do this exact thing, thank you so much, i will keep this close to me because i know it will be incredibly useful in the future
Thank you again!
Haha, I am here now :]
you may not be looking to these comments anymore but i wanna say, im gonna be using your tutorial for the game im working on, and this is perfect for what i have been needing to do. currently trying to work with a subterranean style of a map, always up for learning how to do that more effectively. also all my thanks for these tutorials
Thank you very much - enough slowly paced tutorial without being overly lengthy while still being plenty educational..!
SIDENOTE: FOR ANYONE WHO HAS PROBLEMS WITH THE "Symmetrize" function, you must have named the bones to be mirrored, with the .L or .R suffixes.
_L and _R also work :)
I named with .L at the end of each bone and still not working.
Does it just symetrize some of them?
I've found the solution: If naming isn't the problem, select your armature in object mode and navigate to Object > Apply > All Transforms.
Fixed symmetrize for me, hope it helps!
You probably won't ever reading this comment, but thanks man. Videos are simple to follow and this is very well explained! Everything was working good on my side
Thanks for this mate, this is the greatest fps arms tutorial
Hey man I just wanted to say thank you for a really amazing explanation of rigging, great video. IK setup was particularly confusing to me until I watched this video, so thanks for making sense of it.
You are a complete lifesaver
You deserve atleast a mil subs if not more
I spent more than an hour trying to figure out why the bones weren't Symmetrizing, only to find out that i only needed to add .R at the end of the name of every single bone.
But still, great video!
This is truly a wonderful tutorial. thank you very much! and for those who have or will come across the problem with the automated weights heres my fix since nothing happened when i pressed ctrl+p and tried to move the ik bone in pose mode : before you press ctrl+p to automate weights ,select the arms mesh go into edit mode and select ALL vertices with a (having the vertices mode checked in the upper left corner). then press m and merge by distance.. it removed two vertices in my example that sneaked themselves in. so merge all vertices by distance and then do the step with ctrl+p automate weights . have a nice day
👍👍👍👍👍
it Worked for me! ThankYou!
i love you
I think this will help me greatly... I have a project for a portfolio while learning blender and this just will come like a glove!
Thanks so much! :)
Nice, good luck
Its crazy how much progress ive made compared to other videos on this site
good job man! continue please!
Will do :]
Helped so much thank you keep up the good work
Thanks
Thank you a ton, your videos are seriously saving me right now. Thank you.
I've tried 3 times now and up until 13:26 it all works, but when I do the automatic weights, it gets all f***** up. Suddendly the opposite bicep moves when I move an Arm Target and none of the forarms are even connected to the armature. When I switch to weight painting all it shows green on the right hand and the rest of the vertex groups are just blue.
Has anyone experienced this?
I anyone else is having this issue, it's because the normals are out of whack. Go into edit mode while having the mesh selected, select all by pressing A and then shift + n to recalculate normals. After that, my auto weights worked like a charm.
@@Properpeanut Thank you so much, i've been trying to figure this out for like 3 hours and its finally working. holy bro!
Fun fact, this was the first series I ever watched when I decided to start playing around with unity outside of VR Chat. That was back around May or June 2023, and it's hard to believe how far I've come since!
Thanks for helping me kickstart one of my new favorite hobbies, you rock!
Great tutorial, I am not going to use Unity but this turotial is still very helpful, thank you
For anyone who has trouble with the mesh squishing incorrectly, make sure to take the time to figure out the weight painting, it helped me fix it.
When symmetrizing the only bone that got copied is the IK target and pole
Earned a subscriber very good videos for these arms
For some reason I had some kind of issue with the global positioning when using the symmetrise option. The armature would duplicate but not go on the opposite side. If you have this issue then try the following. Select the armature in object mode, under Object, Apply, click Rotation and then try fiddling with those.
Another thing to watch out for is that both arms normals both the same, otherwise you might experience differences between the arms. Spent hours looking for the problem, turned out it was the normals were flipped (one red one blue).
If anyones having problems with parenting the mesh with the arperture, and esp if youre using a higher poly mesh -- it might be a topology problem and fixing it on 1st level of subdivision is much easier, so just check any problematic areas you might have with the higher level mesh and spread out/tidy those areas before subdivision. Easy and it worked for me
I'm experiencing this and I can't fix it :/
Manged to copy and paste all of the bones work to another file with mid poly, it worked. However, the bones are not attached to the bicep, so everything else moves besides the biceps
They are not influenced by each other?
@@SingleSapling Thanks for your reply, much appreciated. I managed to fix it by recreating bones in the mid polly arm. However, too bad it did not work with the high polly arm, it have more details and looks better.
@@SingleSapling Something weirder happened tho with the mid poly, when i selected everything to center it with the origin of the axes the mesh got all messed up and ruined the shape and everything, very weird. May have to just use a low poly but i really wanted to use a higher poly 😢
If Symmetrize isn't working, and none of these other fixes have worked, try applying all of your transformations and then symmetrize. It's also possible that it was caused by my orientation being different (using different axes than in the vid). This fixed my issues.
thanks man it worked for me :D
@@rocketman-f3 glad to help out!
its not working for me any other fixes for this?
Maybe check that the origin point of the armature is in the center ( that the left side of the rig is indeed to the left of the origin point) dont know if that will help at all but its worth a try
@Asdafadas Qwe fandas I'm not so experienced, and this is just a guess, but try looking at the names of objects. It has helped me before, to label them like "Arm. L" for the left and "Arm. R" for the right.
Just a small thing that can be easily overlooked, like applied transforms, global vs local space, axis orientation, etc sometimes it slips my mind.
Other comments probably have more useful info
Don't be worried about starting from the beginning again if you can't find the issue, this has saved me more time than not.
I'm just wondering if anyone had this problem - The 'IK.Arm Target' bone does not rotate the hand as expected. If e.g. I want my wrist to rotate around like it were a helicopter motor, it just doesn't. This makes animating borderline impossible because of the limited movement. The 'Palm' bone, however, seems to be able to rotate fine in the problematic axis, but doesn't move the hand in any other one. Anyone has some ideas? Any way of improving the tutorial skeleton in this regard?
I've found the solution - The creator is using a 'Damped Track' modifier on Palm bone to copy the rotation of the Arm Target, but it limits the movements in certain axes, it seems like a huge oversight and I have no idea why he has not mentioned it.
Instead, I've used the 'Copy Rotation' modifier on the Palm bone, and everything seems to be working as expected.
Hope it help anyone with the same issue.
I see you fixed your own problem, I havent had much luck with the copy rotation constraint, thats why I am using the damped track one. Nice to hear its working well for someone ;]
Guys if automatic weights doesn't work, hit "Mirror X" when putting on automatic weights and it should work.
amazing video_ thanks!!
12:50 ... VERY IMPORTANT,
Make sure that your root bone is with the other bones in the hierarchy, not in a separate collection. If your root bone is in a separate collection or grouped with another armature, it will not parent properly when clicking "keep offset". Took about 45 minutes to figure that out lol
I have the same problem how do you move it?
@@midnightknight1346 I think you can just grab it and un-parent it from the collection in the hierarchy.
@@WARTORNFPS Yessss thank you it worked
FIXED MY PROBLEM THANK YOU! i had a thought that "Hmm shouldn't the pole bones be offsetted to something?" and then looked for it in the video but i must have looked past it, but when i clicked on your timestamp, i saw it and was like OHHHHHH
having issues with the symmetrize part ??? it's not copying to the other side..
Are you sure your bones on the left side all end with .L
For anyone having troubles Symmetrizing your bones to the other side. Make sure you go back into object mode, select all your bones then apply all transforms (position, rotation, scale) then go back into edit mode and try it again. Mine was bugging out for the longest time and I couldn't figure out why. Hope this has at least helped someone.
How do I apply all transforms? I dont get that part
@@shivc03 Object mode, press A to select all items and Press CTRL + A and then click apply all transforms.
@@KyleWithAnM69 thank you🙌🏽
Legend
In case anyone has my same problem at 10:00
IK Constraint not showing up
What happened in my case is that I was in Edit Mode and I was looking at the list of object constraints. You need to be in Pose Mode and in the Bone Constraint tab.
Hope this helps someone in the future.
Amazing, thank you
If you have problem Not able to Find IK constraint , First confirm that you are in pose mode then you will be get IK Constraint
Best tutorial So far
Thanks
I have a problem, once I set parent armature to the model, left hand is pretty well, fingers work and so on, but right hand doesnt work correctly, when I move middle finger, it somehow rotate ring finger... Or also thumb armature does not connect to the mesh at all. What is the problem?
When I use symmetrise everything copies over except the fingers for some reason? Any idea what could be the cause of this?
Update- No issue other than I am a dumb ass and didn't add the _L to each finger properly so they didn't register. If you have a simliar issue make sure to name them like this Thumb01_L rather than Thumb_01L
@@XGenerationGamer1 Thanks buddy it help me alot 👍👍
I appreciate this
I appreciate u
Thank you my brother
Great tutorial, thanks🔥
How to cover its hand with a glove ??
extrude and color
I cant symmetrize my mesh. When i click on Symmetrize it just copies the bones on the same side as the original ones and then sometimes the palm becomes parent of those bones or when i put them on the right arm they just become broken and the IK Arm target doesnt work anymore and just moves the palm
Did u name them properly?
@@SingleSapling yea i did i just gave up and remade the rig but everytime i remade the rig the past problem would go away but another one will show up
Most of the problem having connection with the IK but now the problem is that the left arm is turned on a side but the right arm is still straight and i cant really turn the left arm back to normal (this is my newest problem)
Auto weighting the mesh doesn't work at all. It does move the mesh around but warps it or glitches out in other various ways.
Seems like u did something wrong, try the discord channel for help
For me i may be in a too late of a version but i cant fine inverse kinematics can anyone help?
i have a problem with the Automatic weight thing it says ' Bone Heat Weighting: failed to find solution for one or more bones'
Help
😭
Symmetrize is flipping it the wrong way, it stays on the same side and just runs parallel with the left arm. I named the bones correctly and rotated the arms in every direction and its still the same result. Anyone know how to fix?
when u symetrize there should be a small box in the bottom left where u can change the direction
Select your armature in object mode and navigate to Object > Apply > All Transforms.
the right hand gets all weird when i go into object or pose mode
Press alt+r and alt+g, let me know if that works
@@SingleSapling no, still like that
Can you define what you mean by weird :]
@@SingleSapling the right hand does a 180 and also stays upside down
13:30 if i want to shift right click the armature i ''Set 3d cursor'' how do i select the armature (and they get the blue outline)?
Select the mesh and then shift select the armature, thats it
Hmmm I learned a lot from you as a beginner blender man 😅
Hopefully you will learn a whole lot more :]
@@SingleSapling we gonna follow u until death :)
@@a.technology1446 Oh yes we will. He is the best teacher for blender on yt. Like fr!
@@Arachnid_Racing Wouldn't say for Blender but for Unity + Blender? Absolutely the best.
i've got everything to work up until you parent the targets and poles to the root bone, my rig bugs out when i try to move the hands in pose mode
Probably set the iks wrong, did you try and remake the rig
@@SingleSapling It takes like 10 minutes just to name all the bones, and you want me to remake the intire rig?
i have the same problem and its not because iset the ik up wrong, because initially it worked right, then it started becoming buggy with the hands, there is a better solution to this problem than remaking the rig because something is causing this and it's not the IK
@@samuelhugo3387 I've never had this problem and I did this dozens of times. Try and join the discord and see if someone has a fix
Remake the rig, don't worry about naming everything, naming isn't necesscary.
@@coffee-beast-99z well i geus, i just heard that it's good practice to name them, but the point i was trying to make is, that if i redid the intire thing everytime something went wrong then I would never finish, i should rather learn how to fix problems than redo my work becuase learning how to fix problems is how you inprove, Anyways i did end up fixing it thanks
Having an issue with the IK constraint on the Forearm bone. Whenever I move the Target bone, the "elbow" between the Bicep and Forearm bones won't bend so the arm remains straight.
I have the IK set to the same values:
Target: Armature
Bone: IK_Target
Pole Target: Armature
Bone: IK_ArmPole
Pole Angle: -90d
Iterations: 500
Chain Length: 2
Use Tail: true
Stretch: true
Weight Position: true, 1.000
Rotation: false
Influence: 1.000
I've tried re-rigging it to the same result, really cannot figure out what went wrong :(
Nevermind, I got it working! I never moved the elbow bone tail backward slightly
@@ghostboy986 how did you got it working?
I must have messed something up, because literally nothing works for me. The left target bone moves the right bicep? The thumb moves the index finger? What is going on?
For anyone having problem with buggy when moving IK, try unparent the IK controller bone
I love you
you are king
Thank you so much, i love you
for some reason when i shyimitrize the bones it just duplicates the yarget bone and the pole bone
Did u put .L on the other ones?
When symmetrizing all the Right side bones pasted on top of the left hand bones instead of on the right side. Does anyone know why this may be the case?
Did you name them properly?
Select your armature in object mode and navigate to Object > Apply > All Transforms.
@@bekek7135 thank you!
12:19 the symmeterize not working, it doesnt show the other bone. only bar on down left
when i connect bones to mesh , the elbow doesn't do breaking move. Before that situation everythings same with the video. Also when i click the mesh and bone, mesh edge color doesn't seem blue. How can i solve this?
Hey all, why aren't colors saving? From the previous clip, when I switch from the UV tab back to Layout, the colors are gone.
I canr parent the bicep bones to the root bone, because i canr select the root bone in edir mode. Only in object mode
Pls help, i have the root bone separated in an amateur and the rest in a different amateur, how do i move the rest in the same amateur as the root?
Just parent the second armature to the root with ctrl p, use the "bone" option in the popup
When i do this i don't have the meat stick tab or bone chain tab as I think its called
nvm
Okay, just dont tell on me to your dad 😬
@@SingleSapling DAD!
This is perfect.
Nice
@@SingleSapling yes I just now followed this tutorial and now I have what I want.
Great
when i added the IK bone and used the target, everything works but it doesnt bend at the elbow. Why?
In edit mode, move the elbow joint a bit backwards and then try
The Automatic Weights don't work for me. It warps the model in a way its not supposed to(the arm folds as if it has no joints and the finger bones warp other fingers as well) how can I fix this?
try doing envelope weights
@@thebadboy2002 i tried, it fixed some thing, but fingers still dont work how it need ti
For people with the same problem. In my case some faces on the mesh had inverted normals for some reason so i just recalculated them.
I have a problem, when i move a bone, the hand moves to but in a diffrerent direction and does not follow rotation and location, it goes where ever it wants. Second problem is when i move the finger bones, the bone pulls part of the next fingers with it. i tried weight painting but it does not work like yours.
same, my hand model moves in weird directions
same but my arm also refuses to bend it just curves out
Regarding Symmetrize, mine did not copy IK constraints from left arm to right. Fixed by re-making them on the right in the same way - worked ok.
Excellent! Work for me
Thank you so much
Making the armature the parent of the mesh with automatic weights made everything wrong. Moving the bicep affects the bicep of the wrong arm, moving the wrist bends the whole arm beding the wrist, and using the IK pole makes the entire thing twist. The weight paint tool doesn't help either, as it's still treating both arms as a single large object
what do I do?
Hmm, apply the mirror modifier and then try and auto wp again. Make sure you unparent it first
@@SingleSapling Thank you, the arms get treated as separate now
I'm still having to go through and manually paint in the weights because the auto ones mess up the fingers really badly, I even deleted the hands and redid them from scratch and still no luck there
@@SingleSapling I don't know if you still reply to comments, but I still haven't fixed this can you help me
Maybe there are some duplicate vertices, select everything, press M and then merge by distance. It could also be that there are holes in the mesh somewhere or interior faces. Cant really tell by just the description
@@SingleSapling thank you! I just sort of temporarily fixed it by using the other type of weight. By the way, I’ve moved on to your gun tutorials, but I have one question - should I make the gun sort of tilt up as if it has recoil in the shoot animations? Right now the slide/barrel just moved back.
Thank you!
Can someone help me because when I go to move the arms with the bones the arm doesn't bend it just curves out and the bicep bone moves out of the arm and glitches out the other arm so it would really help me if someone could explain what I'm doing wrong or how to fix it?
i only have with envolope wights in 13:34 please help
Hmm Thats good
The Automatic weight thing doesnt work on me... Everything begins to jitter and the root bone moves for some reason
What the hell did you do?!?
@@SingleSapling idk man:( Im new to blender...
@@SingleSapling I fixed it(somewhat). Well now it animates very weirdly... When I move the finger bone, the whole arm moves with it
@@SingleSapling I think the mesh is for some reason not connected to the Elbow bone thing... Can you help me out?
I weightpainted high poly arms, proceeds to not show said weight paint
Great tutorial! But my fingers first bones does not work at all
It doesn't work, if i try to move one of the hand the all mesh get wried
You need to apply the modifiers first
@@SingleSapling thanks
thanks really helped
my fingers are not attaching well to my mesh. i tried to weight paint but its pulling other fingers and looks terrible ;-;
When i move my target bone nothing happens, it only moves itself
U sure u connected it correctly?
@@SingleSapling i made sure it doesnt have a parent, and i set it up correctly in IK
@@SingleSapling Quick update, i fixed it
@@SingleSapling i found a new problem, for example when i move the thumb then the whole arm deforms, and when i move the target bone in one hand, the second hand will expand and deform
Hmm, did u have the mirror modifier on the model when u added automatic weight painting?
I dont see the ik in tracking on the object of constraint tab?
Should be there, are you sure you are in the correct tab
It's not fair, I modeled a hand twice and tried using automatic weight paints and both times they incorrectly painted whereas everyone else using auto paints gets it perfect and i have to do it manually and still screw it up!
bro the automatic weight paints are so buggy for me 😭Its messing everything uppppp
whats the version your blender?
2.92 I think
Anything after 2.8 will do fine
These tutorials are fantastic! When I try to put the bone in my arm though, it collides with the mesh and refuses to go inside of it. If I try to rotate or move it in the arm, it straddles on the outer edges of the arm and ends up in the wrong place with the wrong rotation. Any idea what's going on? How do I turn off the collision? Thanks in advance!
I solved it, turns out I had snapping on from when I was retopologizing. Big brain moment right there.
Biiiiiig brain :P
I cant find inverse Kinematic THIS IS SO FRUSTRATING!
Go to pose mode and select the thing under the bone icon
@@gotnoja2000 Cheers mate, was looking for a solution for this for way long than i'd like to say
Greetings! On the part, where you do a symmetrize, i got my rig in the same spot. Maybe it is because i didn`t connect the root bone ( just copied the bone from "Object mode". Can I fix this problem or I need to do completle all of the parts again? Thank you for your videos also ^^.
Symmetrize is not working for me
At all or does it do something else
i think i fucked it up, I have a high poly hand with like 100 000 count faces even more, when i want to parrent with bones its freeze, is there anyway to fix it.
You have to do retopology first
After I add the damped track constraint, it doesn't let me add the target bone
Edit: I started over and this time it worked perfectly. Guess I'm a bad listener lol
exporting is a massive pain, i have to manually move the gun to the hand which create a variety of problems. why the fuckk this is an issue i don not know
Thank you so much for posting the video! One problem though. Every time I try to animate the arms, they bend in the wrong way. For example: the right arm, instead of bending inwards towards the chest, it moves backwards to your back. I did start on the right arm instead of the left, so maybe thats why? but I'm pretty sure everything got oriented correctly.
Hmm, before you weight paint, make sure that the elbow is bent a bit towards the back
Hey, Absolutly love this series! I never managed to rig things and it always turned out wrong but this time it worked! I have one problem tho, and the root bone doesn't move the whole rig at once and follow the ik, and when you did it in the tutorial there was no ik being applied when the root bone was moved, would be very happy if you replied
Did you parent both of the upper arms to the root bone
@@SingleSapling yes
Hmmm, i would delete the root bone, add a new one and then try parent the arms to it again
in min 11 didn't work any help ?
good lord the auto weight paint is no where near close lmao dont tell me i actually have to do it manually );
No of course not, just adjust the bones a little and try again
@@SingleSapling damn that was a quick reply, basically stuff like the elbow isnt connected at all because the forearm painted to nothing and for some reason the finger bones painted slightly but to the fingers next to it, not the one its actually inside. cant figure out how to get it working properly
I heard some other people got this problem, what worked for them was to basically remake the whole thing. Although you could try just remaking the ring or copy pasting the mesh and rig into another blender project to see if there is still a problem. But again safest bet is to remake the whole thing sadly. Good luck
@@SingleSapling thats exactly what i did and it worked for whatever reason
Sometimes Blender just says....no
It is not working
Which part

U parented it with ctrl+p?

tnx man that helped me alot |

does it work with ue4 as well ?
I dont see why it shouldnt... good luck and lmk
