Indeed, I do, or at least I did see a lot of detail texture warning messages.
I had posted a message about it and got no response. I sent an email off to
support++at++multigen.com and they recommended that I remove my .attr files
associated with the texture files to get rid of the messages. I did that
and now I don't get the warnings but in light of what you said, I assume
that removing the .attr files didn't really fix anything. When you said
"if the problems are corrected in the multigenfiles..." are you suggesting
that I do something to my database to fix this? I'm not well versed in
Multigen but if you hum a few bars...

Once again, any help is appreciated. And thank you Richard for your most
