Hi there I have another question regarding textures. I get this error when I try to bring in a texture on a object. The object works but the texture doesn't work and the object turns out black when the track is loaded. Just for your info I use Maya to model the objects and assign the materials in there as well. i have included a picture as to what the error message says.
...per chance is your ubs_1.dds image size at the 2^2 format (i.e. 1024 x 1024, 512 x 1024, 64 x 64 etc) ?
