/3/ - 3DCG

I'm currently learning blender for making game assets (vehicles, buildings, weapons, etc), but I'm curious about materials and textures, and tools in general.

Let's say I made a 3D model. Where and how do I apply colors and materials and bump maps/uv and etc?
- In Blender itself?
- Do I export the mesh to another program and paint there? (substance painter???? is that a thing?)
- Use a game engine (UE) to create materials?

I feel like there are so many options for painting models. I guess I'm askign for some kind of overview or tip on how to approach this.

super noob here

How do I set up where parts of a model rotates? Like pivot points or rotation points.
Like the wheels on a car, or the spinning barrels on a Gatling gun, or the turret on a tank.

I'm able to create minecraft-tier models, but I wanna get those models into unreal engine asap so I can start to play around.
