When do you retexture in Unreal vs import from 3dsmax?

Can someone explain the material process in Unreal engine?
Is the proper way to texture in unreal is retexture everything from scratch in Unreal or can you use the textures from 3dsmax?

Thanks!

Unreal doesn’t have texturing options, the typical workflow is that you would create texture maps in another program and import those files and create a new UE4 material where you would plug in those texture maps and then apply to your mesh. You can only apply textures and basic colors, there’s some other unique type of stuff you can do if you get really technical, but stuff like painting a texture isn’t something you do with UE4.
