Okay. You guys have gotten a bit off topic here. I'm not trying to prepaint an area. I know how to do that already. I personally use prop_paint_bombs to do that, they are fairly versatile.

Look at this in game shot of my map in progress: (I'm hovering in noclip)

BIG spoilers ahead but I don't feel like even blacking em out because this last part of my map is starting to piss me off and I need to solve this problem, among others.

So. The player has already used the blue paint to get the box and activate those lightbridges with a box button elsewhere. The player is done with the blue box and must now paint the bridges to get to the exit. But the paint on the floor leads to an illegal solution, so I have a bunch of sprinklers around the walls to wash it off when the button has a box on it. I am using the sprinkler_jet particle for that effect.

Like I said before, the trigger_paint_cleanser does not remove the paint already there. All it does is end up blocking the intended solution which involves portaling the floor to paint the bridges.

Now, I have considered using paint sprayers set to "erase" around the area, but I don't want any paint blobs to be visible. I can't make paint sprayers spray invisible paint (at least not without some modding) because there is no flag or parameter for that. The only parameter that comes close is "draw only" and that has the exact OPPOSITE effect of what I want.
And I can't have them just spray once while the player can't see it because I need this to be a continuous effect.

Soo.... this is a dilemma. Remember, in the end of the original portal2 SP campaign, right before the stalemate button these sprinklers come on to put out the fire in the stalemate resolution annex, and they wash away all the gel except the white directly under Wheately, and there was this cool dissolve effect. I want that. I'll settle for being able to do that WITHOUT the cool effect, I just neeed to keep those surfaces clean for the last part of that chamber.

also: lol at the deleted post =)

In the info_paint_sprayer's options, there is an option that says "Paint only", which means that it will not draw the paint blobs or the splashes, and you can turn off the noise as well.

nope look closely the option is "draw only?" I don't see "paint only?". Directly under "Draw Only" is "Paint Type" which has to be erase. Like I said, Draw Only? does the opposite of what I want.

I feel like there is a "paint only" option. It might not exactly be named that but i REMEMBER using it before.

Yeah got it working. This is lol. Create an info_paint_sprayer and set 'silent' to True. It sprays the gel, but the blobs are invisable and dont make any sound. Its hilarious. I press the button and the floor just turns blue lol for no raisin.

I still think that PAINT_SPHERE is more elegant. Also no blobs, no sound, and if need to paint or erase a big area, only one is needed (or maybe 4 extra at the four edge since it paints a circular area.however one water drop should be visible that falls down, because it will become weird how they just disappeared.

Yes thanks iWork925. The option you want is "Silent".

ok i'll try either way in a test map. I already have sprinkler particle emitters set up around the area so "just dissapearing" won't be a problem.
