Okay, here's what I think was going on - When UVMapper exports a file, it originally wrote five digits to the right of the decimal place. When the numbers get small, this can cause a significant loss of precision. I've changed it so that it now uses eight digits to the right of the decimal place. It will lead to somewhat larger files, but does fix this problem (I may make this an export option in the future.) My best guess is that Poser didn't like some of the facets because they became non-planar with the loss of precision. Anyway, the new version 0.23h is available now at: http://home.pb.net/~stevecox Please let me know if you have any problems with this new build - Cheers! stevecox@optonline.net
