What I"ve done is import the model into 3DS max..pose it..export it. Set it up in the G.E.C.K & this happens with the textures on the model. I've tried renaming the textures to my own file names or even using default and I"m still getting this issue.

Any idea?

From the looks of it, the game isn't finding the textures. Double check the file paths in the GECK and make sure it's looking in the right spot.
