Shadows with matte objects and vray sky in CPU mode

[francomanko]

Hi,

I was just messing around with getting shadows in the alpha using vrayobjectproperties and matte etc. I noticed that if you add a vray sky, in CPU mode the shadows are yellow (with default sky settings) . Disconnect the GI and its white. This doesnt happen in GPU, that renders white.

So couple of questions

1. Is this a bug
2. If so, have I found a bug thats not GPU but instead CPU..and if so do I win a prize

Ive attached a scene. Image shows the alpha channel with yellow shadow.

It is normal. GI on mattes is not yet supported in V-Ray GPU, hence the difference. It happens with regular lights as well.
