I want to export every face in my 3DS MAX Project as it is a map and I want to assign textures within Unreal. If I do not detach the faces then the map will act as a single mesh, because the map comes from the Source engine. However, the faces are there, so I just need some guidance on how to export every single face separately.
Don’t do that, that will create too many objects which increases draw calls and lowers performance, You can apply your materials in 3ds Max, but make sure to use as few materials as possible, ideally one material per object and keep the number of objects as low as possible.
