Well for most things I normally just do textures in the modelling program (Maya). As I’ve realized, or have yet to figure out, how to apply material to just one face of an object in Unreal Engine. I think it’s possible using UV’s, but that’s just more work for doing something simple like adding one texture to a face (of a wall), and another to a ceiling face. I’m just trying to figure out what the best work flows are from A-Z for VR. I’ve been modelling and animating for years, but obviously then for rendering, where performance was never an issue in the final product.
But thanks for your reply! Not sure how having a single mesh or having different meshes doing the same thing would impact lightmaps? Whether the ceiling and wall are connected or separated it should not make a difference? Or am I missing something.
