Hello!
Is there any method in Material Editor to use at least half-res downsampling on a custom post process materials? Some post process materials such as blur or lens distortion may be really heavy because of computing every pixel on screen which is a waste.
Didn't found a single material node about that, but I found some shaders in Engine directories such as:
Both of them claim to be "PostProcessing down sample". But is there any practical method of using it? I should clarify that I'm not exactly good in HLSL just at the moment.
Thanks in advance!
