hi
i only just noticed myself but since the update the matlib files of craft have had the mats renamed!
if it was "chrome_102" and it was renamed it to "chrome" the the matlib file, outerra seems to have renamed it to "chrome_102" again! so it cant find the textures! as the dds file is "chrome"
EDIT: never mind, not a bug! i had re imported the other day and forgot! thought it had happened to another file too but was wrong! ignor this post! my bad!
