Setting sections for custom unreal engine textures and etc.

Hello, community. I’m in the process of making and video game. I’ve made a mesh successfully in blender: a room made form a cube. What I want to do is be able to make the textures and etc. in unreal engine then blender. Also making my sections separate so Ill be able to paint each one.

Actually I figured it out quite simple. Great to be in the community.
