VrayAmbientLight to reduce GI flicker

[vlado]

Ah? I just uploaded 1280x720 clip. There is no other things to do. But in case of 720p, it's not good as original.

Hm, didn't work for me What video format are you uploading?

Best regards,

Mostly I use mp4 and avi.

Thanks and sorry for the digression

You're welcome! But I saw so many 720p clips on ChaosGroupTV youtube channel. How they do it?



ps) And I posted the other thread too, you're right. vlado.
My problem(render crash) is due to RAM error. I changed it and no problem so far. Thanks

I'm trying to reduce the flickering in a huge forest, while also reducing my precalc/rendering times.

I can't find any documentation on the VrayAmbientLight and I was wondering if the following approach would negate the flicker issue and allow me to lower my rendering settings?
-Add a VrayAmbientLight to the scene with a VraySun as the light map
-Completely excluding the forest object from the GI calculations
-Exclude all objects from the VrayAmbientLight except the forest
-Add VrayDirt to the forest texture to add some detail

Would this also shrink the size of my IRR and LC files?

Hi,
I just have an animation in the same way to do with a tight deadline !
I just try this method and it seems to be ok but but the rendering time is beyond what I can... How can I do to optimize it ?
Thx in advance

Another question ? It's a good trick to reduce GI flicker but at the expense of rendering time ?
I mean use a VrayAmbientLight will inevitably be more expensive in time ?

In my case, rendertime was saved a little.

Yes good question.
@rikou: It's been a week and a half, have you had same results as sandykoufax in that your rendertimes are less? Or in your case using the VRayAmbientLight took longer to render?

in the VRayAmbientLight mode, do we use "Direct + GI" or only "Direct"? Does that mean it will calculate GI or fake it?
