Warpper shadow catcher, dome light and GPU mode - could it work?

[Micha]

Hi,

I read that the wrapper material only works for lights in GPU mode, not for GI. So, is there a way to use it with a dome light? I don't got it working.

This should work out of the box for V-Ray GPU.
Please make sure that:
1. The Wrapper material's "Matte for Secondaries" option is disabled. (alternatively, simply grab the "Matte Shadow Receiver" from the preset material library)
2. The Wrapper material's Alpha Contribution is set to "Black Alpha (-1)"
3. Dome Light is set to Spherical shape.

(shadow in the illustration is slightly exaggerated using low-intensity sunlight)


Kind regards,
Peter

Great, got it. Thank you very much.

Again - fresh scene and fresh options. CPU mode works, GPU doesn't work.

Sorry, at my last post I have overseen that I need the light dome.
