====================================
If you're getting started with modeling in Blender, these are the 6 key tips you have to know to get your skills to the next level.
There is a lot of noise when it comes to 3D modeling in Blender, but it can all be simplified into a few basic rules that apply to any model you are creating.
1. Form (0:28)
The first thing that you want to think about when modeling in Blender is the overall shape of what it is that you want to create. This might seem obvious, but it’s the most important and often the most tricky part to get right.
Any form in Blender can be made up of simple adjustments to cubes, spheres, and the other primitives. You don’t always have to block out your model first, but doing so may help you get unstuck. Even if the primitive blockout is unusable in final production, it will help you understand the underlying structure of what you’re making.
2. Detail (3:06)
So you’ve got the overall form down, and now you’re ready to really push your object to the next level. But when it comes to detail in 3D modeling, it’s important to know exactly how much and what kind to make. Whether you’re modeling for a mobile phone game, desktop game engine or for a short film that will take hours to render makes a huge difference in what you can model.

3. Scale (5:11)
Try to model to real world scale whenever possible. The size of your model makes a lot of subtle differences, from how the lights in your scene behave to how simulations will interact. Most importantly though, it forces you to be consistent. Exporting to other programs, adding procedural textures, adding bevels, or appending objects from another project will all just work like you would expect.
4. Adaptation (6:37)
In short, your mesh needs to be easily adaptable to design changes and to however it will be animated.
5. Reuse (7:56)
I don’t think anyone enjoys doing work twice, so we’re definitely not going to like doing it 300 times. To save time, reuse as much of your mesh as you can. This can mean using a mirror or array modifier, using Alt+D instead of Shift+D to make an instance instead of a duplicate, or duplicating and altering an existing object instead of starting from scratch.
6. Surface Quality (9:25)
This is how your object looks when rendered. Because of how rendering works, how you model your object has a big impact on how light interacts with its surface. Be on the lookout for bumps, pinches, and warped areas. These are signs that your topology isn’t supporting the form of your object.

@Mathew Phillips I've worked in Maya, 3DS Max, Autocad, etc - principles are your best friend. If you start with any of the apps (Blender is free + CG Cookie is great) and model a few things you'll have a better sense of what you eventually want to use or purchase regarding software. CG Cookie is great because they're always reminding you of industry standard modeling and art principles so you can take the knowledge beyond the app. I spent too much $$$ on a degree from a major art university and am still constantly going back to CG Cookie to refresh principles that I learned at school from industry professionals. Blender Guru and the broader blender community are great (great forum responsiveness), but CG Cookie is a great value if you have a few bucks to spend. Good luck and happy modeling!!!

20 years ago ... well ... 16 years ago (I shouldn't age myself more than necessary) when I first started working in 3D, I had an accomplished modeler (guaranteed 85% of you have seen his work) gave me the most valuable piece of advice that has saved my sanity in the years since. - " *Your model details need only fit the use of the model. If a deck of cards will only sit on the table in a stack, why model all 52 cards* ?" Sometimes we get caught up in the challenge of modeling highly detailed models. If you model strictly for the challenge then by all means model every single card in the deck. But if your model has a purpose, such as an animation prop, a game content prop, or detail for a "still" then consider how much detail is actually necessary for that model to fulfill it's purpose. If a car rumbles past in the background, you don't need to model the interior. You probably don't need to detail a lot of the trim of the car and let the applied texture do most of the work. Maybe you will know the car doesn't actually have chrome trim around the windows included in the mesh, but no one else will know that.
Lol, production schedule will teach that lesson too. If you’re modelling out things all day that wont be rendered then your production coordinator will show you out the door pretty quick.

Those principals have been applied to movies for many years; If it ain't on camera, don't build it! Some of the spaceships in Star Wars / A New Hope / Whatever, were only painted on one side. The one facing the camera.
This is also called "Keep it fast and dirty" :)
Oui
Finally!
A tutorial with no obnoxious intro, no "WhAtS uP guYs ItS yA bOy hERe TodAY wE arE LeaRninG X"
And no screaming into the mic.
Just a chill, straightforward tutorial.
Thank you!

Dude which blender youtubers do you watch
I think you might be watching Xbox hacking tutorials instead of Blender tutorials
i dont know were you find those tutorials but in kinda 8 years years ive never found something like that beside gaming channels lol
Reuse is an excellent tip. I finally got sick of creating a mesh with proper face topology and a rig (I prefer to use my own) every time I create a new character. So I made a blender file with a topologized face mesh that I can shrink wrap to a sculpt. It also has a basic body mesh which I can modify as needed, and a full rig with IK and bone shapes. There are two different styles of teeth -- cartoony and more realistic. I combine everything together and apply the rig, getting rid of anything I'm not using. Now I can make a new character, fully rigged, in about half the time it used to take, because I've eliminated all the repetitive tasks.

Ha! Loved the rendering transition!
Same😅
Well said, I am a begginer to 3d and it can get way to complicated very fast. Keep it simple and don't give up. Thank you.
Well said on YOUR part as well. I'm in the same boat and I totally agree.
Haha, yeah me too, after 8 years of learning.😂
Perfectionism can be a pain sometime! 😅
Always helpful. I'm just a hobbyist but remain addicted to Blender. Your tutorials are always the best.
Thanks
Thats the best addiction ive ever seen
Can we appreciate how good this man sounds on a SNOWBALL???

No I want to make a baby chicken in Blender. I got the hair part done pretty good on a sphere. Next part is challenging. Then I am going to make an animation where the baby chick gets ground up in a blender. Do you think that's weird. Well it's a true story. In the egg industry baby male chicks are ground up alive, because male chickens don't lay eggs. The same thing happens to baby male calves in the dairy industry. They are killed at a few days old.
DO YOU WANT TO MAKE AMAZING OHRT!?

I just started learning 3d modeling yesterday. I tried learning it once but got overwhelmed. There’s an open world game jam I found on the internet that I’m using as a way to learn the basics to unity and blender and to make my first 3D game, even if all I can do is walk in it. So far I have followed a tutorial for a basic road, and I made the basic structure of a simple house by myself last night. I still have so much to learn, but as a gamer, I’m excited to be able to make my own worlds and stuff
Been involved in this for 25 years now, and just wanted to say your video tutorials are extremely well done.
Bros been doing 3d modeling before blender existed 💀💀💀
Brilliantly straightforward tut with really valuable information.
Can we all just take a minute to admire the detail in 8:28?
Both it, and the wall from 4:26 to 5:02 had me HURT
I would sooo love a tutorial for that
3 million faces. Woah.
honestly, its actually not THAT hard its just a lot of work. I found for me that seeing every part of a model as an individual asset helps a lot. For example when making a bike, (after you do the Block out) you dont do a bike, you do a pedal, then you do the chain and later you merge them all together into a bike. Also imagening it being SUPER large, like if you make a gun try and see it from the perspective of an ant.
Crazy how Justin Timberlake got into 3D modeling
I was looking to see if anyone else thought that...
Hahahaha OMG!
He got time but he don't mind 🌐✨
Music industry is not worth anymore 🤣🤣
Lol
Thanks for putting all the extra info in the description and breaking down each part of the video into chapters
Blender should bring back randomize in the array modifier. I remember some build couple years back and it was way easier to make a tile floor have a big of randomization :)
I wrote a java program YEARS ago that randomly offet the vertexes of a model by a set amount, as I needed it to generate rocks. I have no idea where it is but it was quite a simple program, as long as you use a simple model format. Surely someone has written a python script for that in blender.
@@rich1051414 Yep thats is true and BLender already has Randomize in its menu's. But this was in the modifier, which was super handy
you can basically do anything like that and more with geometry nodes, ive been trying to learn it (although slowly as im very busy) because it is a very powerful tool that ik will be very useful once i get it down more (its already been very useful with creating environmental details that need randomization like grass, rocks, trees, etc). And geometry nodes is modifier based so you can play around with your details later down the line!
I'm actually working on learning 3d modeling with the hopes of getting a degree in character modeling, so these points are really helpful! I'm relatively familiar with them already thanks to the course work I've done, but seeing them in action in a condensed video really helps drive it home. So thanks for that! I'll have to look into the mesh modeling bootcamp after I get home from work.
Your intro anim is so professional! Simple. Short. No annoying long music. Half of the youtuberts could learn such simple basic things from you.
Your contents also one of the bests.
6:53 Design for adaptation can apply to materials, too. For example, using shared node groups for related materials. So for example if you want to change the shininess for all those materials, you can do it just once in the node group and have it immediately take effect everywhere that node group is instanced.
So the next time you select a whole bunch of nodes and go shift-D, consider turning it into a node group instead.
I've gotten so used to Blender's new UI that the old 2.79 one made me jump
I got so used to blender 2.91... imagine my horror when I saw that blender 2.92 came out...
I have to install... a whole new version??!!? Absolutely unacceptable.
@@dogol284 just wait until 3.0 comes out
I love the aesthetic of blenders random color visualizer
I really appreciate this video, thanks for putting it together!
Excellent lesson and great pacing. I've followed your tutorials since the early 2000s through your Digital Tutors era and this best practice video is amongst the best.
Wow, thanks so much Ernest!
Been doing this for 4 years but this is still helpful thanks lol!
3D modeling for 24 years but watched (almost) the whole vid. It never hurts to listen when pros are sharing their insights.
I must say that every time you have the blender-render scene transition, it cracks me up.
more like universal creativity/problem solving principles. very well done. thanks for sharing.
Excellent video!! It’s aways great to see videos like this. Its so important to have a base-line for fundamentals and practices. Especially if you’re new to 3D. Thanks for the great advice! 👍
Brief and to the point, good stuff.
I decided to use the basic blockout approache on a model recemtly. Its helpfull to get the shape and idea out and not worrying about the topology that will come after tge idea and form is solidified
I tried the tip of first making a rougher draft and then going into the details and made my previous horrible attempt into a pretty good looking one, this video is really helpful, thanks ^^
I think reuse is one of the most valuable lessons here.
Great video. That really helps. Keep up the good work.
Thank you for the advice, going to apply these principles in my future modeling!
Thanks for all the good tips!
Thanks, this was great overview, with I'd watched this years ago!
incredible dude, thank you so much!
Great quality video. The information provided and how its communicated is perfect. Thanks bro
I just subscribed. My path has just started. Years ago I learned Poser and Bryce and was going to graduate to Maya and Lightwave but I had to choose other areas of learning. I recently learned about Blender and I finally have time to learn it. Your teaching style is perfect. Thanks for making it free.

what a GREAT video. thank you.
Great job and content. Thanks for sharing.
very cool. Any architects or interior designers watching this and feel like these rules just naturally came to us and we don't even need to think about them?
Cool tips, thanks i knew about most of them, but still learned very important things ;)
One of the best videos for newbies! No one explained to me exactly just how much detail is too much and I encountered queite a few problems because of that ^^
Even though I don't do 3d modeling, this video still helps a lot with traditional art, hell maybe I'll try learning it
Thanks,
A big help for me and to others also.
oh my god that Neil Blevins link. Perfect exactly what I wanted super helpful Thank you
Yay, glad it helped!
Great video. Thank you!
Excellent tutorial. Tx.
Thank you so much very helpful
Yes, I need to improve my modeling skills before moving to pbr shading.
thanks for the modeling advice, it really helped me identify a few steps i was missing
I'm so glad it helped!
Very informative and well presented, thank you! Extra kudos for the transition:-)
Thanks Gergely! 😊
Thank you Steve
Thank you, that's really good value 👍
Excellent tips
Thank you for the tips.
Starting 3D modeling for 2 weeks now and just discovered this video, I did everything wrong 😂 Thanks for the wise advices!
Great video. Thanks.
5 years of being a construction engineer has prepared me for this 3D art and using it for game development
I started off with blender as a beginner but had to watch intermediate level tutorials because I was at an awkward stage where I have experience in CAD in other softwares for other purposes
Superb video, very concrete tips
Great advice, many thanks
Nice tips! Thanks!
GOOD VIDEO, and it's good there are informations in description, so it's easy to remind!
I work out a series of simple, quick technical drawings before modeling.
Thank you! This helped massively :)
This is exactly what I was looking for
Thank you!
This transision its so much awesome! 1:00
Thanks very helpful.
this guy should make a skillshare class
Thank you so much I'm consistently making all these mistakes you mentioned
Neat, this is inspiring me to try getting into blender again.
2.8 is awesome! Very tablet friendly, please do!
Excellent video.
After many years of illustration and a very short time in 3D modeling I agree with everything you said. I have not been using sculpt because I like to block out the model with cubes, using subdivision to work in detail. This is working for me except when I need a round shape combined with a flat one. At this point I am duplicating the file and then appending the needed part into the master file. That seems to work but maybe there is a better way?
minor point, paint the wall under your background under the black and red square black, that will keep the white areas from showing.
Thank you 😊😊
That transition is great
We went to school together. I knew I knew the name. I remember being blown away by your “Enforcer” model/render. Congrats on all the success!
i've become really fond of the old subsurf+extruding & creasing method lately, rolling with 8 segment circles because you're smoothing them out later anyway is quite lovely, it usually cuts the UV maps of the original primitives right for you too
besides, extruding then punching in the numbers is a good way to get exact measures in blender,
then you just select P separate to make parts a new model as you go along.
if only solidify worked on things without faces... skin does work on edges, but the corners don't quite look right
so i usually just extrude a skinny plane around, and bridge some loops if i care enough
but i usually just overlap them, and abuse merge by distance / remove doubles to stitch things together lol
THanks for this! Very good and clean video! Will watch more of you °u°
Thank you.
Learned this in elementary school and i need a refresher
this was tight. Thanks
Pretty useful, thanks a lot)
Excellent, thanks, just subscribed
8:44 And of course the new feature in 2.8 of creating collection instances.
nice eye contact
thank you!
very helpful!!
Thanks buddy 🙏
As someone who has only recently started working with 3D Modeling, id like to pass some of what ive learned so far onto someone else who is new.
Start small. Dont try and model the empire state building and every room. Model low poly stuff first to learn how to use all the tools, then try and do more and more complex stuff as you get further into working in 3D.
I started 3D modeling by creating low poly retro game models, then started doing more high poly models when I felt like I was able to. I probably would have quit if I had tried to do high poly stuff from the beginning.
Gonna have to bookmark this lol great tips my man
very informative, thank you!
Yay, I'm glad it was useful!
Excellent video.. !!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you!!
8:43 WHAT THE HELL THATS SO DETAILED HOW LONG DID THAT TAKE HOLY GOD
thank you thank you thank you!
You know what blender needs? A hardware shelf where you can put industry standard fasteners, and chain links, and screw threads, or whatever (grass, leaves) so you can find what you need easily and fast; outside egde measurements instead of just vertex measurements; and a bit in the physics panel, or nodes, or something with real world materials so you can select, say 18-8 stainless steel and it will automatically set the color, texture, weight, strength, etc. I'd pay a fair amount for a pack with these three add-ons.
Chocofur has an asset manager addons that you might be interested in.
