oxytrees flicker

nelpiper · June 9th, 2008

Hi guys. I'm doing an animation where I have lots of onyxtrees and bushes. Unfortunately, they're flickering a lot. Does anyone have any ideas how to fiz this? Thanks.

Are you using custom textures for the leaves? Is anything else in your scene flickering? What renderer are you using?

Give us some more info...

nelpiper · June 9th, 2008

Custom leaves. I'm using vray. Just vegetation is flickering.

what are your sampling and AA settings in Vray? ...also, are you using UNC paths for the mapping of the leaves?

nelpiper · June 9th, 2008

Yes UNC. AA are adap subds: -1/2, ir: medium 40/30, lc:1000

what settings would be recommended for a nice free flickering rendering animation? Thanks.

Is your lighting precalculated? Or are you generating new Irradiance maps for each frame?

In the vegetation-heavy animation I finished a few weeks ago, the key wasn't so much the individual AA/GI settings as it was precalculating my lighting.

I'm calculating ir and lc separate. My mistake, the are no texture for the leaves. Just pure color.

I've made another test and no trees or bushes are generating or receiving GI. It's exactly the same thing what makes me think that GI is not the problem. So, if GI is not the problem, any ideas what could it be? Thanks.

This might be a little late but how is your DR set up? If one machine isn't seeing what the others are seeing, then it might be the problem....
Hope you found the problem-Gary
