rendering global ilumination
im having problems rendering with global ilumination turned on.
i made a scene with a sky and i had to the sky a material that has a hdri image.
the problem is when i render my scene the objects appears to glow like an intermittent light
what i mean is that in every single frame the surface of the objects change and dont stay with the constant light/shading that it suppose to be
i hope some one can help me
thanks -

Is it a still render or an animation?

an animation

Yea that happens…a lot. If you search the forums you will find the question a lot and not so many answers. I remember a few longer threads at http://www.c4dcafe.com where some ideas were shared but results were project specific.

what GI Mode are you using? If it’s Standard you will want to read the manual -> Modules/Advanced Render/Global Illumination/Parameters.

If all or most of your illumination is coming from a texture source and you’re using standard (not stochastic) GI, you really need to amp up the sample count and quality to minimize flicker. Of course that means long render times. At some point it may make more sense to use stochastic mode with low samples along with scene motion blur, which helps to blur the samples.
