View Full Version : optimizing what?

Can anyone tell me what "Extra Ray Trace Optimization" under render options does?

the only differnce I've noticed is that it "optimizes" the objects on every frame, which tends to add a fair amount of time, which strikes me as less optimal.

Just curious what it is about.

It add some time, yes, but it will increase the speed at which rays are traced. If you're using radiosity, it will quite often decrease the render time a fair bit, even with the "optimizing mesh" thing. If it worth using in a scene or not, you'll just have to try once with and once without, and see which takes the longest.

It's fully explained in the manual (p388 in the European manual), but you should avoid using it if there aren't any transparent surfaces in your non-radiosity scene because it might slow down rendering (since ray tracing doesn't need to be done).

Thanks guys. Its nice to know what those buttons that don't seem to do anything are doing.

I noticed both of you are a fans of "ye old chrome ball". Here's another one I did awhile ago...
