this is eating up 8.5ms and I can’t find anything at all in the documentation or online about it, it’s something in the post process but I have DoF off so I can’t think what else it might be
It’s used for lens flares.
You can look at
Engine\Shaders\PostProcessLensBlur.usf
Engine\Source\Runtime\Renderer\Private\PostProcess\PostProcessLensBlur.cpp
Engine\Source\Runtime\Renderer\Private\PostProcess\PostProcessLensBlur.h
to see the code.
thank you
I guess my lens flare settings are somehow not ideal
