Yeah, I had to put sparks back in in many places too.
What I do is I go through the cleaned scene and the original layered in difference mode, which shows the parts they have in common as black and highlights the differences, so I can see everything that’s been erased and shouldn’t have been.
After this, I’ll need to give it a manual cleaning pass as well, because a lot of the dirt is still there.
Can we look forward to seeing something like this in your despecializing video 😄?
