Title: UHD splotches - hdri+CoronaSun
Post by: joonior1985 on 2017-10-04, 11:17:20

Hi there,

there is some problem with UHD cache. In scenario with HDRI + CoronaSun it generates splotches. Have a look at attached images.

Already solved on FB by switching to "animation" uhd preset, right?

It may be interesting to find out what is causing these artifacts, so if you can share the scene with us, please upload it to https://corona-renderer.com/upload and notify us at support@corona-renderer.com

I've just sent a scene file. There is one conclusion that appeard:

In Development/Experimental Stuff there are 3 types of light solver. "Better Object-based" is set as default but as soon as I change it to some else problem disappears. I don't know how this particular parameter affects the rendering so I'm a bit worried about changing it for final rendering.

Thanks for reporting, it seems it could be an issue with the new light solver. The dev team will gladly take a look.
