Render Mask not working at all in VRay Next GPU

[D3Pixel]

Hi, I am trying to render a part of a model on an interior but it seems to render that part in colour but fills the black area in noise. the noise is in the alpha channel too.

Is this completely broken?

Here is a shot where I have changed the colour of the part I want to render to blue.

I have tried every mask option in that list and the result is the same noise ridden result.

Hi,

Can you send me the scene and describe step by step what are you doing to achieve this?

Hi I can not, it is a client project. I will look at a sample cube scene today and see if it is the same.

We can sign NDA if this will help.
