@mradfo21 It's texture based, so for the pixels location all the texture elements used to make the flare like the bokeh shape the ringing the rainbow is all positione accordingly.
anamorphic lensflare ghost/bloom rendered in screenspace from an EXR sequence in Blender, by spawning a shader for every pixel using geometry nodes after culling most of them for optimization (renders in real time for the small lights but slows down with larger ones.)
After months of research, I have completed my procedural lens flare simulator for Blender 4.2!!!!!
I will create more lenses over time, I am currently working on Sirui 50mm Anamorphic Flare
