As far as I can tell. Trying to give you a quick fix. Is when you apply the texture in Bryce. You must also apply the Trans map as well. On the MAC this can be achived by creating an alpha map and saving it as a 32 bit pict. and then adjusting in the materials requester. I hope there is something similar in the PC. If not I guess you can load each map seperatly (texture and trans) in the materials requester. Also play with texture rotation if things look a little screwy. I hope this helps, and sorry for all the miss-spellings, I'm in the middle of xmas stuff too, and writing this in a hurry. James
