Override material and GPU mode bug

[Micha]

At this page https://docs.chaosgroup.com/display/...eatures-Lights I read that the override material should work in GPU mode, only the env feature isn't supported.

But I get the GI material visible at the final pass in GPU mode. In CPU mode it works.

I found, the bug appears if I add a semi transparent emissive layer to the ground material.

This is already fixed in the core.
The fix will make it in the next release.
