Hi all,

I'm having some strange artifacts with Direct Light Sampling Cache:
I've created this blend file with the error:
Edit: Have cleaned the file.

Best regards.

I guess this has been exposed inthis thread
viewtopic.php?f=4&t=705
and corrected in the latest daily build (not sure about this one)
Cheers

Hi,

Thanks for your response, I've tested it with this build and the same happens.

It is a different problem I'm currently investigating.

The .blend file is missing the textures.

Is this the, hdri/skylight cache sampling issue? Can this be solved without fiddling with warmup samples?

Sorry, I cannot redistribute the textures.

If you want to download them, but I've cleaned the file posted above. It also makes the same artifacts but without the textures.

Regards

Hope this helps


1. It only happens with the Sky.
2. It gets more prominent with 'Use Ground Color'.
3. Goes away when Ground Color is set to Black, while changing Ground Albedo Color results are fine (w/o splotches).

Edit: Missing description for Albedo versions: above is Black, below is White (if in doubt, observe sky coloration).

Very strange, I will check: it sounds like some kind of normal-related problem (aka taking light from "down" instead of "up").
