for the face room, here's a trick that might work (I've used it in maya, and no I havn't tried it yet, but hopefully my track record with educated guesses is getting more support, lol) one thing to try is do a render, of the face on the non-matching body. (it helps to have all ambient lighting if poser uses ambient light?) when you're done you can use photoshop or other image edit program to check the color difference between the 2 textures in the render.Since they are in the same lighting the pixel difference will be the same relative. then go into the material editor and use a color math node to add the differece the skin texture (alt-click on the color's box to bring up an editor where you can enter an exact numbers to r, g, and b for the difference between the 2 textures! could work until they can patch...
