Textures seemed to be loading fine up until TI's recent update.
Was reading around and saw that I should recook the map for textures to show up properly after this update.
Unfortunately, after doing so, everything still defaults to the white and blue default engine material when in RS.
Went back into the editor, made sure I had no map errors, recached materials, loaded packages, didn't save any packages while cooking, recooked, deleted shader caches, recooked again, but the textures still don't load up in cooked map while in game.
