I noticed that you can put any amount of post processing materials in the Blendables list but there seems to be no use in it at all?
I would like to use 2 post processing materials at once with the 2nd being on top of the first. So if the first has outlines in it and the 2nd has distortion in it. The distortion post processing material would distort the first including the outlines.
The orange outlines of the editor get distorted when using a distortion post processing material so my guess is that it is somehow possible.
You can set the Post Process Blendable Priority which will draw one on top of another as you are wanting if they are applied to the same place in the Tonemapper Path, higher numbers draw on top of lower numbers. For example, if you have 3 Blendable Materials, one set to After Tonemapper (Material A), and two set to Before Tonemapper, one of those set to Priority 0 (Material B) and one set to Priority 1 (Material C). Material A will draw on top of both Material B and C because of its location, but Material C will draw on top of Material B because of its Priority setting.
can you use 1 post process as mask for another? say the first is a black and white high contrast PP, then the 2nd one would only appear on the white areas?
