What is the difference between exporting Ce in a Bind Export VOP, feeding a Constant VOP into the Ce input of Compute Lighting VOP and feeding the output of PBR Emission VOP into either the Ce or the layer input of the Compute Lighting VOP?
It seems like even if I don't feed the Ce from a Bind Export VOP it into Compute Lighting it gets... combined/computed somehow (additively?).
The only other difference I notice is that I am only able to turn off emissive as light source when I use the PBR Emission VOP. Is it possible to do the same if I am just using Bind Export VOP?
I am using PBR engine by the way... super curious about what is going on under the hood.
