Composites a rendered picture back through the Paint tab's feathered mask, so only what you painted changes and the rest of the image is untouched. Pair it with RedNode Paint Out and put any renderer you like in between.

Name	Type	Default	Description
image	IMAGE		whatever your renderer produced
paint	RN_PAINT		from RedNode Paint Out. Carries the original picture, the mask and where the region came from, so none of it needs wiring twice.
strength	FLOAT	1.000–1	How much of the render lands. 1.0 replaces the masked area completely; lower blends it with what was there, which can rescue a result that went too far.
run_token	STRING		leave this empty. The Paint tab's Generate button fills it in for its own runs. While it is empty this node sits out, and the renderer feeding it is never executed, so an ordinary queue costs nothing. Clear it and press Generate to paint.
