Hi hopefully I'm missing something obvious here but I can't find anything like a paint bucket tool in COPS, I was hoping to fill a section of a texture from the outer borders that would propagate over empty pixels. Something like a flood fill algorithm: https://en.wikipedia.org/wiki/Flood_fill [en.wikipedia.org]

Hi FFD,

you could either try to write a custom python node in COPs or simply use the new group expand-node.

Thanks, that works great. It just seems like something that there should be a COP node for. Unfortunately I'm not much of a coder anyway. Just out of curiosity why did you say python and not VEX?

There are some ready-to-use python libraries containing flood filling functions.
Also a compositing program usually rather supports keying instead of flood filling.
