i scalled up a full ten times because I was dealing with a big heap of what ynsaen is referring to...close up of complex model with heavy texture, bump map and procedural materials and intense Firefly settings. I was getting artifacts. When I scaled up, the artifacts went away (with the addition of a slightly larger shadow map) but I then discovered the benefit of the faster render time. It's simple...the more fine detail you have, the deeper into decimal-place calculations you go and the unhappier Firefly gets. It bogs down and in the end actually does not calculate properly, that's why you get artifacts. A script to scale everything up in a currently existing OPScale (orginal poser scale)? That seems like a valuable script, even more so if the camera/keyframing can be adjusted (I am not optomistic about that). But.... What about the concept of permanently working as OPSx4 or OPSx10 as standard operating procedure? I will be testing this out because I am building many new scenes for a big animation, and believe me, I will be rendering at OPSxsomething. So far the biggest 'getting used to' is that pushing the camera around takes 10 times more mouse dragging....wait....can you scale up a camera? More later.... ::::: Opera :::::
