I don’t know if this method (if you can call it a method:P) has been posted before but I couldn’t find it in any search results. Yesterday, I had some huge problems about the lightmap of a model I made. And just for the heck of it, I tried a silly thing if it works. And well, it worked! I still don’t know how this is possible but if anybody out there that has some problems about lightmaps, shadows etc. just try this silly method. Maybe it will work in your project too.
All I had done was moving the UVs out of main UV window in maya (in UV Texture Editor). So that the UVs will be seen as blank in Unreal. But the model has the same UV settings that it has been in Maya. Strange. Anyone who has an explanation I’d like to hear it!
