Hey folks,
Obviously, with a bloom shader like BloomAndLensFlares [Bloom.fx] there is a fBloomThreshold where "Every pixel brighter than this value triggers bloom" is determined.
What I'm looking to add is a 2nd Threshold that determines "Every pixel brighter than this value triggers no Bloom"
The reason I would like this option is I like the effect of a very low level of Bloom coupled with a very low BloomThrehold AND I like to utilize HDR.
The problem is that using a bloom shader with HDR leads to the bright areas being blown out, typically leading to the sky/horizon being a mass of pure white (blindingly bright!)
Does anyone with experience of creating custom shaders know how this could be done (or if there is already a bloom shader knocking about that has this option)?
Thanks to anyone who takes the time
Here is, I think, the relevant code of the existing Threshold section from Bloom.fx
