how do i import a texture/uv map for my model? I make morph targets for PoserPro, and  for a while one of the heads I was sculpting was allowing me to turn it on 'texture shaded' and let me see skin texture instead of just a white figure. But now when I do it, it just turns blue. I don't know why. Is it because the figure is now using a PSD file for textures? 

So can someone tell me how I can get this working again? Is it because of the PSD file? I have it saved as a PSD in case I need to edit it again. 

Forgive me if I'm not using the right terminology but I'm not great at the names of things used in 3D models
I'd just export the texture as a normal image format from Photoshop. Therefore the original .psd file can still be changed.
You should be able to keep the Texture coordinate - as long as you don't drastically change your texture, new exports will still fit onto your model
