thanks for the comment , i lost all my save file but i start remake them in hammer i will consider this

It indeed is too hard because you have to paint everything. I guess if there's a small puzzle before the main puzzle where the laser has to go all around before hitting one catcher, it will change the mindset and people will look into doing that, and if all angled panels on the ceiling have paint, this can be the visual clue. It would still be a hard puzzle, but the trial and error part would become more obvious.

i admit this one is to hard.

Holy dang this is hard. To have to resort to a screenshot (which I have not seen) and to paint all the walls and then do trial and error? You've taken the fun out of this one and made it incredibly tough. Sorry to say but this is a fail. Your other chambers have been good though.

well when built something like this it is very hard to know if it to hard or not because when you built you don't have to think in the same way. I guess i try to simplify it.

I just looked at the solution because I just can't get this right.

My answer: Seriously? You expect us to be able to come up with this? Sorry, but this is a downvote. this is not a logic puzzle anymore. this is plain luck if you ask me.

@: Donderbus: try this one it is more an obstacle course tell me if you like it.

If the solution in the screenshot is the intended one then yes, for me it is to hard.
But it's not the kind of test that appeals to me, sorry. I like your other dual laser tests because I could see the solution but in this test I would need to paint everything and then, with trial and error, try to get all catchers.

Was it to hard ?

I saw the screenshot... why did'nt I think of that...

that is a cool a picture of the solution. The blue portal is on the ground.

Well I started thinking about weird solution including laser reflections... But I gave up after being killed by the multiple lasers reflected in all the room XD Maybe I will try again later ;) Good reflection puzzle indeed ;)

I think I fixed the bug with the reflection gel dropper already. Check that you are using the latest version of my mod.
