RT vs Production Renderer Bug

V-Ray V-Ray GPU Issues

If we have the production renderer set to Irrandiance map and change to RT, the result in VFB is wrong.
If we have the production renderer set to brute force and then change to RT the VFB is correct.
When we render with the full production rendered (using either irrandiance or brute force) this matches the RT mode ONLY when the production renderer is set to brute force.
I hope that makes sense please see attached.
I think this is a bug, I didnt think that selecting different engines in the production renderer affected the RT renderer, but it seems to be happening here.

Hello,

If you mean ActiveShade RT - it uses the GI settings from the production renderer. Also it supports Irradiance Map only from file.
So if you’ve set IrMap as your primary GI engine and start ActiveShade - it will fallback to Brute Force GI.

Thanks Yavor,

Yes I mean Activeshade RT, I didnt know it defaults back to brute force.
I will have a look at it, and it could be we have a from file map in the IR slot.
