Thanks again Edward,
I now turn motion blur off in all layers in the render settings as I do not see a solid setting for that.
I returned all PA solid layers to 2D. I was thinking I would make PA objects usually from AI files and then navigate by them in a 3D AE setting. To do that they would need to be 3D solids, but perhaps that was the time hog. You suggest that is not a recommended use of PA.
I started getting lower render times, especially in draft/half res mode. However, I started getting that “unable to allocate image buffer” failures. I followed all of the many suggestions for that in this forum, but I still get them or either AE crashes.
I think I should just start the development of this comp over with fewer PA solids. I see that I can put multiple tracks in a single PA scene. I have just been using it for one object at a time and have 13. If I could lower the total number of PA solids, perhaps that would get me operational again.
thanks for your help,
fred
