Ridiculous colours

[REDVERTEX]

The bug appear in one of my animation scences. Nothing unusual than the previously tested vray settings. No probalistic lights, no hdri, the lighing of the trees is "baked" in the self illumination slot of the materials(no gi casting though) All and all 4 lights in the scene. This is the second time i am experiencing such bug. About half a day extensive testing and still not sure from where it appeared. The colours are strong and in only one gamma - when the splotches appear they are red, or green, or blue. At some point i started thinking that it is some kind of mistake in the calculations in the irradiance calculation. it appears in the irradiance pass (not the light cache) and afterworth in the passes regarding it - total lighting , gi, etc. Any ideas what can couse this?

Are there any warnings in the V-Ray log? Any raytraced materials or map? Any Standard materials?

Best regards,

Usually if I see those round dots like on the wall, it's a standard material in there somewhere...

The scene was converted, and has no standart materials in it. About the Vray log, the small ammount of tests when the image is ok i get massage for wrong light cache sampling.

I would really love to get a scene for that - can you send it to vlado@chaosgroup.com ?

Its gonna be a wild guess from me, but since it appears to happen in the leaves, could it be the bitmap/alpha or some treatment to those maps that you are doing? Generally I would look at that shader and see what could be going wrong there.

check the output amount of the diffuse texture.
