Way to check/switch on Lumen being activated in a material?


been playing around with lumen and noticed that emissive materials glow a lot more when it is activated, compared to “no lumen”. (I pretty much divided everything by 10 to get similar looks - thats how big the difference is.)

Given the performance cost of lumen, we will need to have a “fallback mode” for years to come in our games, but then we will need a function/switch in materials to switch the emissive multiplier depending on lumen being enabled or disabled.

Do we have something like this (couldnt find anything), or is there a way to create a material function that automatically does that? (I can do it manually, with some trickery, but its not really practical.)
