There are several good tutorials here. I don't remember the links, but search around (or maybe someone else remembers). All the answers above about mesh glitches and patches are correct. I've found, (and maybe I'm just doing it wrong), that the textures, trans, and bump maps never come over right. In (Windows) you can select each body part separately by Ctrl/Clicking to list everything under the cursor. Then check what material is actually loaded for that part. Eyelashes are particularly tricky. [I could go into more detail if needed, but others understand this better than I.] For things with transparency, like hair, don't forget to check the "Blend Transparency" option in the material editor. Another thing is that bump maps in Bryce are similar to height maps, with value == bump height. In classic Poser, bump maps (.bum) are entirely different, and will give very dissapointing results in Bryce. Often both types map are hiding somewhere in the textures. Also, it seems best to set the bump channel to around 10%. Much more becomes really coarse. Again, I may be doing this wrong, or there may be a better way. It's a lot of effort, but the results can be worthwhile. You've asked in the right place. If you'd post a detail of the render you are having difficulties with, I'm sure we could pinpoint the problem better.
