How to import material into Unity?

Question

3D

There is a video on YouTube where models are imported from 3D paint, and Unity itself generates all the material, but when I import it, it erases all textures leaving only the shape, I understand that paint is not the best option)), but I need to whip up drawings on geometric shapes, but I can’t draw textures. Maybe someone knows other programs for similar purposes, in which you can generate textures separately?

Answer 1

Well, assign the textures drawn in Paint to the material manually through Unity
