Spawning paint spots
First of all, wanted to thank this community for your help 
. I reached a milestone of 500 subscribers on 1 of my testing maps. I need your help once again.
Q: How can I spawn a paint spot on the wall?
Let's say I have a puzzle and it should include a bounce gel spot on the wall with no paint sprayers around. I had the idea to spawn a paint and trigger push it on the wall, but I'm interested in an easier solution (if there is one).
Thanks!
Use a temporary sprayer that's killed while the player is still in the elevator. There's even a flag to remove all the effects but the final splatter.
Ok, that's what I thought. Thanks 
Besides the technical side of the question I'd like to discuss a logical one. I never considered that to be a good puzzle idea. How the hell did that paint spot get there if there's no gel dropper around (even in a map)?
My point of view: if you realy want to have a paint spot somewhere in your puzzle, design your map so that there was a gel dropper in a chamber and player had to bring paint to that certain place by any available means.
I assumed that there was a sprayer under the panel and it was flipped around, like one of those portalable/nonportalable walls.
I've never actually gotten paint_sphere to do anything. In the only place where VALVe used pre-placed paint, the final boss battle (during the pipe explosion), there are temporary sprayers in front of the panels.
There's also pre-placed paint in the first old aperture area tests. They use paint sprayers too. My assumption is that the builders came in with a bucket to put it there. In modern aperture, GLaDOS probably paints the panels before installing them in the chamber.

True, but Gelocity did this and didn't seem awkward to me.
I'm pretty sure that any gel was painted beforehand. I wonder how gels act over long periods of time. Do they eventually get soaked into the floor/wall? It would be an interesting thing to find out.

Now, that would be cool for some kind of timed gel test, maybe in co-op. But I would see it working better in single player. Here I go beginning a rant...
