So I’ve been getting these “larger” versions of fireflies which I’ve seen many people call “NaN pixels”. I’ve looked through some threads and done things to reduce NaN pixels like decreasing the strength / entirely removing normal maps, lowering and raising sample count, and clamping the blooming, but nothing seems to work. Does anyone have any sort of idea what’s going on and how to resolve this issue?
I have a video here that shows a comparison of the animated shot I’m trying to render with this issue:
It would seem that severely lowering the samples reduces the appearance of these fireflies / NaN pixels, but it comes with the expected noisy frames. Raising the same count increases the chance AND sizes of the fireflies / NaN pixels.
Some other information:
-Using Blender Eevee engine
-Using Blender 2.83 (newest version)
-I have SSR (screen space reflections) activated in the render panel
-Refraction and half res trace in SSR is also turned on
-Zero baked indirect lighting
