HDRI Dome light exclude layers not working with GPU render 3ds Max Forest Pack and Railclone Objects

Hi
I am trying to use the exclude layers function within the dome light settings. I have 2 lights in the scene one for the forest pack objects and 1 for everything else. When I try and exclude forest pack or railclone objects they do not exclude. I have contacted Itoo on the issue and they have said it is an issue with vray and the GPU renderer. I have tried to use the exclude by selecting objects, this works on selected forest pack objects but not on railclone.

Is this an issue with the software or is it not supported to exclude by layer these objects?

Many Thanks

It’s a known issue (tracker ID: VMAX-12885). I’ll try to bump its priority. The only workaround I see is to include everything except the ForestPack / RC node/models.
