Ambient Occlusion - Dirt Shader - need help

[Kissling]

Hello,
I try to generate an Ambient Oclusion Channel but I alway get a white Layer as result.

I've added a Render Element "Extra Tex"
Then I added in Texture the VRayDirt-Shader.
But the result, when rendering, is only a white Layer.

Question:
How do I generate a Ambient Occlusion Layer?

Regards Ronald

It looks like a GPU limitation, works fine if you use Vray CPU.
I've not used dirt in extratex in a while, but in the past "consider for antialiasing" had to be activated.
