How to color an object by sectors?

Question

Unity

Tell me how to colorize an object with different colors by sector? And how to arbitrarily split it into sectors. For example: a cube - I want to split it into 16 sectors and color them with different colors. Like a Rubik's cube.

Answer 1

You need to paint the object through the material (through the texture - then the material is one, through the colors - then for each color - its own material).
To do this, a 3D object must be prepared in a certain way: a uv-mesh must be implemented on it (in a certain way for a specific task. It can be generated procedurally, or textures can be adjusted to it with a shader , but this is expensive in terms of execution time, not always universal, and not needed in most cases).
To sum it up: walk up to the 3D man and say: "I need to change this, this and this part of the mesh. Make a scan / different materials for this.".
