    Hi,

    I want to add some blur to my transparent shader, so I can't use Blit, only GrabPass, and only one single pass. What are the best techniques for this specific case?

    Have you seen this ShaderToy? https://www.shadertoy.com/view/ltScRG
    It applies a single pass Gaussian blur at an intermediate texture LOD level. Maybe this is something you could try? I haven't tried that myself (yet) but that might be worth checking out.

    Sorry for necroing this thread, but has anyone figured out how to do this Gaussian + LOD blur form shadertoy in HLSL?
