I'm having problems with some object in Poser, you can see what happens for example with Clara (the Vespa), some parts point to infinite. they don't appear when I render the picture but still, they are annoying. I'm having the same problem with the teeth prop of NeaP4 and with other objects/figures.

Another problem : I use to change some parts of the body of my character with other parts, eyes and teeth. I take the eyes of P6 Jessy and use them on Posette, I save them as obj, reimport , pose, and change the part (the eye) with the obj. It works but when I save the character in the libraries the new eyes disappear, the old prop (maybe) appear again but with the material messed up. I'm forced to save the character as a pz3 file.

I'll try to downgrade to Poser 7 without service releases and see if it helps, this thing never appeared before, if it will remain after the downgrade it's something on Windows...

I solved them adjusting my parameters int he render/preview window (I realized it after 2 clean installs of Poser ). The second problem, I solved it changing the materials twice ...

Davide about the eye you also can  use the "Groupinp Tool" to make a prop with the original figure like here

With it you can save and load your work without need to change the materials! I think!

I am working with Poser 6 but never had problems work this way!

Thank you John

In Poser 7 there are options for the preview windows, for the graphic card. If I choose to use the graphic card harware those errors appear, if I choose software they disappear. But these errors are not present in all the figures or props   . For the second error: I change the eyes of a figure with the eyes of another one, when I save the figure with the changed eyes the materials of the eyes become messed up. I've to reload the figure and change the material again and this time it works when I save it
