Bug : vrayobjectproperties + skylight portal = artefact

[bigbossfr]

Hi,
I am in a production, i found a bug and i don't found a workaround. So, i don't know if it is difficult to fix this quickly or not.
Create a scene with a VrayRecLight, a sky, physicalCam


Render :


Now, add all objects (but not the middle sphere) into a vrayobjectproperties to separate the render.
Add this setting :



Render :




If i disable the skylight portal into the Vray light, all is fine, but my lighting is false....

Is it a bug ?

If i understand, the vrayobjectproperties show the environment, and the vraylight do the lighting with the sky, and the sky is the environment. So, we have a loop here...?
I think the fix is to do not show the environment created by all skylight portal on all matte surface (created by the vrayobjectproperties or vrayWrapper).

The scene is here :
matte.zip

Maya 2012 win64.

Thanks.

Hi,
Any news about this please ?

Thanks.

Seems like there was no fix yet? In my scene the portal lights are casting blue from the environment on the matte surfaces. If I hide them everything is right.

There is no fix for this yet. I will bump up its priority...

Unfortunately no, we need to fix this bug.

We have the same problem. A workaround with a domelight instead of GI doesn't seem to work either. As soon as there is a vray sky involved the matte surface is broken.
