Use a func_brush. Make sure you also enable the 'paint in map' option as well.

but what texture should I put on the func_brush to make it invisible, but still have paint look like it's painting the panels?

Explain what you mean by making the panel invisible. Invisible puzzle elements will most likely confuse the player.

If you mean the paint, use a trigger_paint_cleanser which enables/disables on an output.

Your idea is flawed. And hard to create. My as well be "how do I create a map which reinstates the dodo bird popultation IRL"

No. My idea is: I want the player to be able to paint the actual surface of the telescope_arm_128x256 model. Unfortunately, that doesn't work, so I need a brush I can attach to the panel_top attachment point so that it LOOKS like it's being painted. I just want to know what texture to apply to the brush to make sure that paint still "sticks to the panel" but you can't see the brush. It isn't quite an invisible puzzle element. It's a workaround.

Try block bullets. The only drawback is you can put portals on them, so make an invisible trigger to block them if necessary. (However it has to be bigger than an actual portal to allow portal placement.)

Lol sorry I thought this was another invisable light bridge thread.

No problem. I didn't know if that was gonna be a good idea either lol

I've tried block_bullets and invisible so far and neither of those work.
