Mesh Caustics Example Post Process Volume settings

[bach44]

Certain Mesh Caustic specific settings (all?) in the Post Process Volume have no effect on the image.
For example
Intensity
Adaptive Photon Size
Adaptive Variance Gain

This can be confirmed by changing a Post Processing value , then checking in the console using the property followed by ?

The value remains the same.

Hi bach44, in this demo, lots of post process volume UI parameter is override by a blueprint called BP_RTX, which provide configurable RTX engine scalability function as well as the suggested rendering quality preset.
