- Using the mesh deform modifier to get realistic cloth physics. The model in the video is a android girl named B2 from the game Nier Automata.
The music in the background is by Sim Gretina. She makes good music and you can find her channel here: / @simgretina
Just a simple tip: Instead of making the deform mesh by hand, you can simply make your cube around the base mesh, subdivide it as desired, add a shrinkwrap modifier to the cube (with the target set to the base mesh) and crank up the Offset value until you get the desired output.
Fantastic idea!
you speak alien languages mate. thats why in symposiums of experts, foreign spectators arent allowed i guess xD
@@keylanoslokj1806 huh?
Yep, came to the comments to say to use the shrinkwrap modifier instead of by hand also.
+Sam Porter what i'm saying is that those outside an expertise hear the experts as if they were aliens.
Man I love B2 and her boyish companion, Snine
Yeah yeah, I know. I called 2B the wrong name for the entire video. It was my bad for not checking before hand.
Funniest comment ever😂
Nice vid once again Liz! What you also could do, instead of making a new cube, u can just duplicate and throw in a remesh and decimate modifer to cut down the polygons. Then do a alt+s scale to inflate it OR just a shrinkwrap modifer with above surface checked. Doing this with a 7 precision deform quality will give you an effortless and exact controll of the base mesh.
Thanks. This will definitely help when I add better collisions.
Way to go bro. This is heaven sent. Thanks.
Thank you. That's really good to hear.
Wow! You rock, man. Working with cloth is so painfull in Blender but this approach makes all that stuff really easy. Thanks a lot for sharing!
"B2"
Lol, isn't it 2B?
2B
Or not to be.
He's playing Bingo.
man this is so COOL!!.. never thanks enough for this
Wow, thank you for the tutorial!
I have two Wings that use feathers as hairs. Each feather also has hairs to look absolutely realistic, but since using an object as hair is creating hundreds of instances from the same object, they all behave exactly the same to forces like wind. So I think I might go with your approach of plugging each feather as individual object with softbody physics into the wing and see how that behaves with the wind. The pitty is, this won't affect the thousands of hairs each feather is made of, but maybe I can do some trick there as well and use a simple texture with alpha for this rather than individual strands of hairs comming out of the feather "fishbone".
Never really comment here, but I just wanted to say, thanks for all the videos dude. You've shown me some pretty awesome tricks that I never would've normally found.
Thank you. That's really good to hear. :)
thank you so much
i love the bisexual flag in your profile pic!
I'm having a lot of trouble with soft body meshes passing through other objects with collision applied. Any advice?
set collision quality a lil bit higher
hey man this was the best tutorial about explaining for mesh deform modifier
and ofcourse realtime cloth physics was very usefull
thank you very much
Good trick there, Lizendy! Well done.
You are a lifesaver, I've been wondering forever how to properly setup a driver for cloth simulation.
how can you put a colition for example in the face so the hair doesnt go through the face? knowing that both are on different mesh?
select the face mesh and go into the physics tab, press collision and it should work
I believe this is going to work very well for NPR works. Excellent video. Thank you!
Damn 2B is hot as hell
YES!!! :D
Pretty cool blender physics trick. I'll try it one of these days. Still learning how to scult in 3D and a vast host of ther things. Thanks for the tutorial.
For some reason, it didn't work when I parented the deformer mesh to the hair mesh. But when I parented both the hair and the deformer to the head bone, voila! Worked perfect when I played the animation. Now playing with perfecting the collision
Good tutorial with a character who's become a recent favorite (for me). Thanks again for sharing :D
Edwin Jun thank you. Her model is really well made and a blast to use.
Did the model come from Steam ?
I got it from Sfmlab.com but beware that site has some nsfw models as well.
Lol, I could already see some suspicious stuff. Thanks for the link and warning. Looking forward to more videos and I hope you feel better, stay healthy.
Thanks. :)
Thank you sooooo sooo much, I love you bro!!! You deserve more subscribers, keep the goods coming, I still new to blender...
Thanks awesome was looking for this cloth pyshics trick a long time.
Its easier to just apply vertex group select the mesh of the clothing and weight paint where you want it to stay stationary red and movement blue then apply the vertex group to the cloth as the pin and it will pin everything red
i love this video thanks for sharing your knowledge
Don't use collision as in the sphere at the end of the video. Use Forcfield on the character. The side effect is, the higher the strength, the slower the simulation. Set the Type to strength and shape to surface. That means you are also adding physics to your mesh. It will be slow and might not simulate in real time, but will definitely help with the collision.
Holy shit it's her.
Man, this was so helpful. Thanks for the vids!
Thanks for the comment. :)
I would really like to see a more detailed steps for the dynamic cloth hair. How do you do that for curves on hair? Thanks.
It's works like a magic for me! Thanks!
That's great, thanks for sharing it with us!
did you do the same thing for the skirt? can you do another tutorial with skirt? :)
Does this tutorial only respond to collision?
The character's face is shaken to the left and right but the hair does not move.
The hair should be effected by collisions, gravity, and wind. If it's not moving correctly try using an older version of blender, since this tutorial is a bit old the the newer blender version changed the way physics works a little bit.
Great video, you did a great job of explaining everything. I have question for you, are you using soft bodies for the skirt as well?
Yes, though now that blender has a surface deform modifier I would recommend using that rather then the mesh deform. (this way you can have accurate collisions)
an* android woman* named 2B*
That aside, nice tuto man :)
Thank you. This is just I need
When you did the data transfer you forgot to mention that you needed to "Apply" the transfer, that fixed my model completely without any extra problems or stuff to fix
I hope you feel better now. 3 years later.
Yeah I'm starting to feel a bit better.
This is really really nice, i sticked an icosphere insinde the mesh with the colision on and now the hair dosen`t clip the character hair anymore
I can't seem to get mine to work as fast in real time (even with a really nice build ;n; ) and it doesn't want to follow. Hair is quite the struggle for me but i've been doing my best to figure it out >.< Thank you so much for your tutorial though!! It helped me get a little more knowledge on how to hair XD
nice tutorial, man. thank you for this.
very informative thanks ...do you know now blender gave up game engine is the animation stuff going to end too?
Smokenboots the animation isn't going anywhere. Blender foundation removed the game engine because it was out dated. I believe they plan on adding a different engine in the future. But the animation is one of the biggest features in blender, in fact the 2.80 beta makes animation a bit more user-friendly.
i would like that lots ...i love the 2.8 beta its so sexy
look into the armory3d engine. it's an in-development game engine "plugin" (sort of) that claims to let you do proper game dev in blender. haven't used it yet but it looks neat. bge was never good for much beyond prototyping and rudimentary physics simulations anyway.
Thank you, this is really awesome.
thank you you are the best
Guys, I'm stuck at the weight painting part :/
For some reason the weight paint gradient tool doesn't work as intended. Instead it paints everything red from top to bottom with no actual gradient happening.
EDIT: Ok found the problem. It's Blender 2.8 being buggy. It worked fine in Blender 2.79
Moral of the story - always keep a legacy version of the software around kids, for when the new and "better" version starts acting up.
Man, lovely character :D
Yeah she is. :D
Very helpful. Thank you very much.
Thanks for putting this video up while you were sick. Hope you're over it by now. I've managed to get 2B into Blender and combine with an animation and music so she dances. I want to turn her skirt into a cloth simulation so it reacts more realistically to the dance moves. I add a collision modifier to her body and a cloth modifier to her skirt and bake. But when I play the animation her skirt falls straight down through her legs and eventually disappears from view. Every other video I've watched with simple square cloths and block obstructions does just that and doesn't run into this problem. Any thoughts on what I'm doing wrong?
btw - Nier Automata is an awesome game so if you want another fun distraction then go get it.
I think the problem is that you need to parent the softbody to the pelvis.
Did you use the deform mesh to get the physics on the skirt too? I have been running into many issues trying to get clothing to do that same movement :/
same here! Blender Physics is driving me crazy.
This is freaking neat!
Great video!
good stuff! thanks.
How would I go about getting the hair to collide with the head? Tho collision modifier isn't working.
my mind has been blown dude
woah, good one.
Great tip!
Hi. I have a situation with a Character I created (superhero). It is in default (designed) standing in T-pose. But when I animate the arms down to the sides of the body, the body-mesh breaks thru the clothing-mesh. Could I send you the .blend file and you can take a look and let me know what's wrong (incorrectly done)? Please.
same problem here... did you get any result?
Very well done, great tutorial. I just wonder how many things I can do with that
Excellent. Would this work in the game engine?
I believe so. Though you may want to keep the soft body object as low poly as possible because it can really eat away at the frame rate if it's too high poly.
That's really smart!
awesome tutorial! I think u got this model from sfm lab but how did u do those materials ? they look waaaay better than SFM ones ?
will it work porting to a game engine, like unity/unreal?
Sorry but no. This is a blender only thing, but there should be other ways to get cloth physics in game engines.
@@Allen3D thanks so much!
Greate video thanks for sharing it. I have a comment on video production. I think it's better to mute the microphone while coughing or sneezing if possible ;) Thanks for the great work. Please, continue uploading.
Thank you, and I agree. I should have put more care into making the video enjoyable for the watcher. I'm sorry for the careless nature of the video.
@@Allen3D Everything is good in the video and you care about the people. Thanks for sharing and teaching us. Please, don't say sorry :) I just wanted to contribute by giving opinion or suggestion ;) I wish you all the best of luck :)
Amazing!
Hi there, thanks for sharing this nice trick!
Just curious, which software are you using to record the keystrokes? I'm trying to record other kind of tutorials on Windows but can't find a decent software :(
It's an addon called screencast keys.
D'awww, I see. Thanks for sharing! I was hoping it was not something Blender-specific ;)
nice idea ! 風邪 お大事に
subbed. epic
Thank you!
So, if I were to use a "bucket" around a collision "head", I could probably run a simulation such that the hair won't clip through the head.
great video
I noticed your hair is mesh. would this work with the hair particle system as well???
Seanfrtd I don't think so. Though you can turn on dynamic hair in the particle settings.
awesome
Is there a good way to make this useful for rigging? Because I'm having a skirt where the legs always clip through, but it's too wide so I can't hide/delete the legs either.... I tried doing this but it never went with the rig and stayed behind, making the soft body collisions really hard to render and even more extrem than cloth simulation clipping.
You can either weight paint the shift body. Or just parent the soft body to the hip bone.
Yeah somehow I'm having a few deforming problems together with the armature for some odd reason. I'll have to look into that more tomorrow - I'm tired XD
It seems to really help avoid clipping through the clothing though, so that makes me happy. For my liking everything just bounces too much but I haven't found settings which make it smooth and still let the clothing go away from the mesh underneath. I'm fairly new so thanks for the advice!!
Mika-hime you can turn up damponing. That should help stop some of the bouncyness. If you need help with anything else I would recommend messaging me on discord, it'll be alot easier to talk to you there. Lizendy #0847, is my discord if you're interested.
brilliant!
We all came here for the "simpulation"
Random question, what are your wind settings? I'm having trouble making mine look good.

I've been looking at this comment for like 3 minutes. I still cant figure out what you mean.
I wanna say a big hi to @Lizendy and a big thanksgiving for the tutorial, very simple and practical! I am new in the world of modeling and I am currently specializing in the modeling of Mythological characters by anthropomorphizing animals for xv2 a game of Dragon Ball. I would like to ask questions about the compatibility of this method to create objects with physic with my game, if this method also applies to clothes and other things. Since I do not want to block messages on youtube, do you have a server on discord or an email where, with your permission, we can have a chat about it?
I'm glad to hear you liked the video. You can contact me at "Lizendy#0847" on discord or "Lizendy" on steam. As for using this method for a game, I don't think it would work unless you use Blender's game engine (it's not that good.) I think the best way to do physics like this in a game engine would be by using bones with physics joints. The bone method will work for most engines. But I don't really work with games too often so I don't know if there's a better method.
Wow!! Thanks!!
the hair did you sculpt it in blender or in another program?
Your tutorial was hard to follow in places, I'm a newbie to blender and 3d mostly too, so there is that, but you need to be much clearer about where you are going and what you are selecting, and not just assume people are keeping up with your tiny cursor, what I made following your steps (including going back and watching things repeat edly) did not behave anmything like what you produced. I don't know if this is because the software works differently now?
I'm sorry to hear that. The tutorial was more meant for people who have a little bit of experience with the UI already, but even then I guess I should have been a bit more clear about exactly what I was doing. Also this tutorial was made over 3 years ago, Blender has had some changes to the physics system as well as a few other things so I wouldn't be surprised if it didn't work exactly the same way. The version in the video is 2.78 and Blenders most recent stable release was 2.83. There are definantly better ways to achieve this cloth simulation now.
@@Allen3D thanks for replying, I think the main thing was the settings for the soft body effect, your movement seemed to be constant rather than momentary, and I can't seem to achieve that :(
@@cdchurcher There could be a few things causing this. Make sure you always start from the first frame, because it works a bit wierd if you try to start on a later frame. Also if it's cutting off after a few seconds that's probably due to the cache amount. This is an easy fix if it's the problem just open the cache tab in the soft body and set the end frame to whatever frame you want the soft body to stop at. Sorry if I'm not very detailed in my explaination. It's been quite a while since I've done any physics in Blender.
@@Allen3D I already tried that but it didn't seem to make a difference, I think that soft body maybe isn't the effect i need, trying to make it work with cloth but not having much luck either lol, thank you though!
@@Allen3D I am gonna take back my complaints from earlier and instead just say a big thank you, I think I was just wound up and after all you were sick at the time and you still made the video, so kudos to you. I've come back to it hours later and rewatched your video, played around with it for a bit and just spent the time experimenting with the different properties to see what they do and how they interact, I've not used this for the effect I originally intended but strangely enough I have used to add some movement to the character's 'hair' (wig). Thank you! xx
Do collisions work for the hair and head?
What if my character is already being deformed by a mesh deform modifier. Can i make a new deform mesh and add the soft body and stack it
I believe it should work. try it out and let me know if it went okay.
Yes, Thanks, It worked perfectly
That's good to hear. Let me know if you run into any other problems.
Thanks bro, been looking for a way to cheat the whole hair dynamics in blender this is awesome... Quick question though, if I set the body mesh to a collision object would that stop the hair from going inside it?
Technically yes, but it will most likely make your hair freak out. Soft body collisions are the most accurate in Blender.
Would this vertice movement transfer to an animation and be exportable to say Unity?
please share the video link of how you made the hair
thanks dude
Always thought cloth simulation was crazy taxing, so i wonder how they make it in the fifa games, when playing on a ps4 i noticed that right away
If you don't mind telling us, what are the specs of your computer? I would like to think I have a decent one but by following this tutorial I can't get faster than 5 frames per second while the mesh is moving in my setup.
Sadly the computer that I used in this video was confiscated. I don't remember the exact specs. But I do remember it had
gtx 970 graphics card and
8 gigs of ram
Try only moving the model in solid shading mode.
I have 24 Gigs of Ram, but a GTX 745 card... I really do need to upgrade that. CPU is actually faster for me than GPU, and that is a sin.
7:28 what's that selection wheel thingy, is there a separate addon for this?
It's called pie menus. If you have one of the newer builds of blender it comes preinstalled. You just need to turn it on in the preferences.
woah, that was a quick reply... thanks and btw your tuts are awesome!
Thank you very much. If you run into any other problems just tell me and I'll help to the best of my abilities.
lol i thought he was yandere dev
how dare you.
i swear i saw that exact model in a porn animation somewhere...
Yes, there are nude versions of the 2B model.
Thanks
No problem. It's fun making these videos.
is it possible to bake this hair movement to bones so we can export it?
is it method used by the industry for the animation
I couldn't get this to work.
But when the character walks for example the sphere stays where it is and no longer deforms the hair... any solutions for that??
You can parent it to the head bone.
@@Allen3D that literally messed up the whole hair.
@@flop9265 Oh crap that's not good. Unparent it and hopeful my dumb advice didn't ruin anything. You should be able to at least weight paint it to the hair. I'm sorry I don't know what exact solution is. I haven't mess around with physics in Blender for probably a year now.
@@Allen3D Okay i found a solution. I moved the proxy object as the head moved with each frame so that hair was completely inside it and locked the keyframe one by one
@@Allen3D but obviously the hair is penetrating the head and i want the head to be the collision object but when i make the head the collision the whole hair gets sucked in and making the inner 0.0001 didnt help either. Any tips??
I got to the point where I'm binding the mesh to the deform block, but once I bind them, they don't move at all anymore.
UPDATE: I'd ctrl/Z'd too far back and accidentally deleted the soft body. Anyways, I got the mesh bound to the jiggly deformer, but the mesh won't move on its own. It only moves when I move the deformer itself. What's up with that?
You either need to reparent the rig to the model or you just need to move your modifiers around. (btw Sorry for answering so late. It's a bit harder to get to a computer these days.)
Are we able to add collision?
Yeah though you might have to mess with the collision distance a bit because the default value is a bit high in my opinion.
@@Allen3D ah alr, thank you for the response!
request tutorial modelling karakter time plase .please help me for training blender
It'll be a little while before I make a timelapse. I'm still pretty new to character modeling. I would recommend looking at other people's timelapses in the mean time. :)
Can i use this trick for hair particle
