Access Blend Weight in custom Post Processing Material
I've got a quick question about Post Processing Materials. How would I access the Blend Weight from within my material (I have tried just adding a parameter named "BlendWeight" but with no result).
Right now I don't get a smooth transition when I enter the Post Processing Volume (I do if I only use the default effects and not my own custom one).
The option you are looking for is the Blend Radius. This takes the distance in Unreal units around the volume at which blending with the volume's settings occurs. Hope this answers your question.
Here is some more helpful documentation on Post Processing Volume and how they work: https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProcessEffects/index.html
