Heya folks,

Anybody know how to do an ambient occlusion/GI pass on pyro smoke. Seems like the method where we create an environment light and set the rendermode to ambient occlusion only works for geometry. Thanks.

Cheers,
Jebus

It does work, you just get a better look out of directional lighting when dealing with volumes.

I guess the new forum only supports a single attachment.

Here is a distant light rendering of the same volume.

Heya, thanks for the quick reply. Works when I render in Mantra.

Are you able to see the AO in viewport mode? I tend to render my work using flipbook because it's faster.

Cheers,
