Light dots Vray

[Anonymous]

Hi guys!

Any ideas why the light on the ceiling is not smooth and why those random light dots in whole picture? The lights on the hanging lamp are Vray sphere, spotlights are Vray disc light, and by the curtains Vray plane. Rendering with Vray.

Best regards, Laura

Hi,

It's not easy to guess without knowing the settings but we can try something:

Try to check the Sub-Pixel Mapping option in the Color Mapping rollout,

Also check clamp output, and try a test render and see the result. if you don't see

those two options click on the Default button to change it to Advanced.

Sub-Pixel mapping should be enough alone by the way.

Here i'm guessing that it's a matter of over bright areas that the image sampler(AntiAliasing)

Is not able to handle. I'm also assuming you're not using any caustics features.
