As the title suggests, I will try to explain myself in a simple way.
I model things in Cinema 4D and then, in order to import them into Unreal, I export them in FBX format.
I realized though that if I export my model, with a uvw mapping, I get a drop in the framerate, it doesn’t matter if the mesh in the scene is static and with all the lightmap baked, as I said, I see a drop in performance during the program execution.
Check, if the same model is always exported in fbx, but without a UVW mapping, the program runs smoothly, but I cannot texturize the model, and after compiling the lightmap it will go completely black.
As can be seen, this thing is not good.
Obviously I need my exported object to have a mapping, but I certainly can’t afford a performance drop.
Someone for some explanation for this?
