Yeah its a strange one bud. I ran a compare of the files and there's no difference between the PC & Crossplay files and both match the files downloaded from this page. Could it be the texture files are not formatted correctly for use on consoles?
Hey Bill, just a note to tell you I managed to resolve the issues on console by adding a normal map, oat_normal.dds from the basegame files to the oat_mat material. Might be an idea to update your pack to add the normal to avoid the same issue on other maps in the future
