environmentfog

[gregvfx]

Hello,

I don't understand how to use the environment fog, in the doc it seems to produce very good results with 8 subdivs but in my case it produces "big" noise, even with a lot of subdivs (512 is not enough).
Is the light/shadow subdivs multiplying the fog subdivs? If you put a map in the light, does the fog has a texture?
It looks like the noise of the fog is 2x2 pixels large... even with shading rate at 16...
I am very confused.

Best to send us a scene for investigation to support@chaosgroup.com so that we can check what's going on.

Best regards,
Vlado

I don't think there is any particular issue. Just that I don't really understand what parameters to tweak...
Basically I put a fake caustic IFL into the light mapping, the map is 512x512 so I left the default parameter. Anyway even leaving it empty it looks like the noise has a 2x2 pixels pattern.
I can send the file tomorrow but again a lot of xmeshs so pretty heavy... I can remove the animated mesh and leave only one image instead of the IFL...
