Hello, I am trying to learn modeling so that I can eventually make my own game assets. At 11:20, you said, "This isn't going to be a game asset, so it's okay if these faces intersect." (not an exact quote, but that's the jist of it)
Can you please explain to me why it is undesirable to have different meshes intersect in a game asset? Also, do you have any recommendations for game asset modeling courses that I could do after I complete this course?
Very gratefully,
Brian Buckman
Hey bbrianbuckman,
I think its undesirable to have intersecting mesh in a game asset because of shading and lighting artefacts.
I would also say that being a weapon that will be close to the camera, the lower quality of modeling would be noticeable.
There are probably more reasons than this, perhaps @jlampel would be the better person to answer this.
There are several courses here on CGCookie that will assist you with game assets,
There is a series of courses for creating a FPS weapons,
Modeling Weapons for a First Person Shooter
Texturing Weapons in Blender and Substance Painter
Rigging a Transforming Rifle in Blender
Animating First Person Character Weapons in Blender
Also there are courses like,
Animated Sci-fi Game Environment Creation in Blender
Creating Mini Tanks for a Mobile Game with Blender
Game Character Modeling with Blender
Hope this helps!
There isn't a hard and fast rule I'm aware of that says game meshes can't intersect, but it ultimately comes down to what the in-game shader needs to do, and what textures need to be baked for it. I would guess he was concerned about UVs and texture space. Usually you don't want to have faces taking up space in your UV map that won't get seen, as it's a waste of pixels. Real-time applications often use those UVs not just for texturing, but also baking light maps, so clean UVs are doubly important.
As for course recommendations, there are a few great options here on cgcookie. Kent has his robot course. It's a whopper of a course, but loads of great info. Jonathan's tank course is a little more bite-sized. Together they give you a pretty good spectrum on game assets from mobile to AAA.
Hey, thank you guys both for all the advice, I really appreciate it. I'll definitely be checking out some of those courses and doing some research as to how to make some good game assets.
It was a problem with my browser, all good already, thanks for receptivity. And regarding games, I access frequently https://australiacasino.reviews/10-minimum-deposit-casinos/ because here I find sources for casino bonuses for $10. I mean I play games of chances and earn money, this is advantageous. Even if some game asset questions, you wil get help there, so try it, guys)
