I'm a bit new to serious 3d modeling, and I have a question focused on workflow and style as opposed to technical tips (which can be found in tutorials).
I'm creating a character model for the game I'm making. Right now, my entire game's art design doesn't have any textures, just different colored materials, so in order to create a nice looking character, there are many meshes involved, i.e. a visor for a helmet, a patch on the character's arm, etc. This is fine until I start animating things and exporting them into Three.js format. Animations don't work correctly or just don't exist at all.
All this being said, I've watching tons of tutorials on the process, and every single one has a character model consisting of one geometry, one mesh. Is this standard practice? If so, then I need to redefine how I make models. Secondly, is it atypical to see material-only artwork? I'm not overly skilled with textures, but if it's a completely uncommon practice, I can abandon it.
Thanks for the time.
