View Full Version : Slow Preview calculation

I'm on a mac G5 Quad running Cinema 4D Version 10, and I seem to be getting abnormally slow preview render times. The animation I'm working on will play at about half real time speed in the preview window if I just hit the play button, but when I try to render out an Open GL preview to view the animation in real time, it takes forever.

I've checked the Open GL settings and everything seems fine, and the interface is performing normally, so I have no idea why rendering out an Open GL preview to Quicktime would take so long. Any thoughts?

One reason can be outputting to OGL or even worse AVI is very slow compared to rendering to frame sequence. But also make sure you're really rendering to OGL and not to software, in versions prior to R10 software was the only option there and made preview renders (playblasts to any Maya friends reading) almost uselessly slow and feature lacking.

Just so we're on the same page: I"m talking about the "make Preview" function, not a regular render. I've tried all the options in the Make Preview window, and nothing seems to help. I don't remember having this issue in Version 9. It seems that if my graphics card can play back the scene reasonably fast in the viewport that rendering with OGL to a Quicktime movie shouldn't take much longer.

Yes, that's what we're talking about. If you're having a particularly difficult scene where it's really showing as being slower in R10 than in R9 then please send it to Maxon so they can find out what's causing the problem (and fix it).
