To anyone reading this thread.... In my excitement at solving my Poser5/Firefly "artifacts in animations" issue, I reported significantly improved render times. Now, after some sober tests this morning, I am retracting. Under the conditions I am working, the render times are about the same, either at the Original Poser Scale or at 10-times scale, keeping all other factors equal. My misconception came because of changing too many factors at once last night in a rush to both solve my 'artifacts' issues and also discover what contributes to slower renders for my type of scene. So, I apologize for the false alarm. I still will work scaled up from now on, because of the artifact problem. See a new thread I am just starting about render speeds. ::::: Opera :::::
