After working with Smith Micro on this it was just decided that it was a bug that had to be fixed. Now they were to fix it in SR1 but apparently it didn't take. They are looking in to it but so far it seems that this bug is still around. The artifacts show up as unrenderd squares that pop up randomly, if anyone remembers this from Poser 5 & 7, it was a glitch that seemed to superimpose the geometry behind the camera onto the rendered image within the camera's view.

The tech at Smith Micro seems to think that this particular bug is a surface rendering problem and is confident that it can be repaired in the future. I must say that this is not a glitch that really impedes progress because it is so simple to fix. It is very hard to see the difference when a single frame is missing. I simply just delete the aberrant frame and all is well. I surely cannot see any difference save there are no glitched frames :)
