Ghosting in volumetric lighting Does anyone know any method to remove ghosting in volumetric lighting? 

When light move it leaves trail behind, i would like to remove it.
Volumetrics are Bart Wronski style (in frustum) with exponential temporal accumulation.

I have tried neighborhood clamp, Karis and variance clipping, both remove ghosting but also introduce other artifacts.
Temporal by definition will ghost. I’d limit past frame sampling, apply weight &lt; 0.5, limit movement etc.
