Finds NaN and Inf pixels in rgba, zeros them, and radially cleans the surrounding area before writing the result back into the plate.
Nan Inf Killer scans the incoming rgba channels for NaN and infinity values, builds a mask from those hits, and replaces the bad samples with zero. A radial MarkerRemoval pass then softens the neighborhood around each hit so isolated spikes do not leave hard holes.
Drop it on plates or renders that break downstream math, grade, or deep merges because of invalid float values. The group is automatic: there are no threshold or size knobs—only the fixed detect-and-clean pipeline and a link back to the author site.
Inside the group, per-channel isnan/isinf checks feed a max mask, the masked pixels are zeroed, MarkerRemoval runs in radial mode on that mask, and a copy merge restores the cleaned result over the original bounding box.
