What version of Poser? I created them in and for Poser 4. If you are using Poser 5, you will need to reference the bump .jpgs instead of the bump .bum files. If you are using Poser 4, you need to created the bump .bums first before using the MAT files. You can do this by opening a blank document in Poser, opening the Material Editor and applying the bump .jpgs as the ground plane's bump channel. After you have converted them all you can cancel out of the material editor and use the MAT files as normal. If you are using P5, you will need to open the MAT.pz2 in a text editor and change the bump reference from .bum to .jpg. I can do this for you, but it will take me awhile as 1. I don't have P5, 2. I have to get to work shortly (bah humbug!), and 3. I don't have the eyes on my system at the moment due to a hard drive failure - I just never got them back on. I'll have to search my cd's for the files. You can either try those suggestions on your own or wait until I get off work tonight and I'll do them :o). Either way is fine with me. Laurie
