View Full Version : Baking shadows in fur

I have an environment using fur as grass affected by raytraced shadows. Each frame plus layers takes about 15 minutes to render. I need to pan through the environment but don't want to recalculate the grass and shadows every time. Is there a way to bake this information in so I am simply rendering previous shadow maps?

Raytracing fur is quite expensive. And I'm not sure if raytraced shadows can be baked. Depth map shadows can be baked.
What are you rendering in btw? Maya software or mental ray? Mental ray has volume primitive option to speed up fur rendering.
If you switch to depth map shadows, then you can always write them to a file and reuse them instead of rebuilding them.

Im rendering in mental ray. I'd like to stay with raytracing as it's too late to switch to depth. I assume that the look of it would change too much, should I move to depth maps now, and not go together nicely with what has already been rendering.
