Look at the length of the names in the texture files. If any of them are longer than 31 characters, the Mac can't open them even if you see the first part of the name. The path to the files can't be longer than 64 characters. (OSX might be different.) So, if you have a texture which says "morningcloak_butterfly_tattoo_texture_for_mistymoistymorningfae_by_martysnookums.jpg" you'll just have to shorten it to something sensible. Carolly
