Where do the SHADER_USE_MIS values change?

Hi there.

I’m tyring to understand where those kind of values are set, because I see the variable “use_mis” being set, but I don’t see where that variable affect the “SHADER_USE_MIS”.

I may be a bit lost, you can already imagine that I’m a bit lost, but trying hard.

My ultimate target is to be able to set the “SHADER_EXCLUDE_CAMERA” for the lights, but I’m being totally unable to do it.
