So in the latest puzzle I made I have a funnel, and some propulsion gel, and if any of the gel gets on the portal surface that the funnel goes through, when the player is right about to go through that same portal the player is dropped, like if the tractor beam got disabled for a second(it doesnt).
So my question is WTF IS GOING ON??
And more importantly, how can I solve it?

Is it possible to make the surface unpaintable?(but the paint must still be able to pass through)

Sounds like you got a bit of a bug there. Are you positively sure that the funnel makes you drop when the surface is painted?

I'm also guessing that you are making the funnel go backwards for the paint to go on the wall. Try fiddling around with the linear force Key Value and see if this makes any difference.

Ok, the linear force thing didnt help, and it only happens when the paint is reversed into the funnel, not if it lands directly in the funnel. This is just super strange. I tried putting a trigger_push there to make you not fall, and it kinda works but you can tell thats somethings wrong. So I would prefer another solution.

I think I remember Omnicoder saying something about that. I think he said he had a bit of a temporary fix, so I would talk to him
