Vray Problems. Black Holes unsharp outline

Hello everybody,

i have a Problem with my Vray Render Engine.
I use the Rhino Sun for lightning my scene and as of late i have these black holes and an unsharp outline to the horizon.
Maybe some of you can help me?!

With best regards,

What you see is the default environment image.
With an exterior scene, you should select the “sky” as the environment texture.

This looks like an HDR / color clamping issue (the pixles in the black area are outside of the 0-255 range). In the frame buffer, if you click the Force Color Clamping button, does the issue resolve?

Hi Sam,

This was the problem! Now i can go on working.

Thank you working.
