I think MAT poses should work with Judy, if you are using V1/2 textures.

If there are no MAT poses, attach the textures manually. You do it in the Material Room. Just connect the texture to the Diffuse Node of the proper material zone. If you're not sure, load up a figure that is rendering correctly, and go in the Material Room and see what the settings are.

However, I must say...if you don't even understand basics like how to apply textures, you really should not be trying to make your own figures. Learn the basics first.
