Another one that I missed along the way. Fun to solve

Slick map.

@sandwich..........Nothing wrong with your game. The Cave Johnson voice should not be there. Some people have the BeeMod ad-don installed so that could be why you're hearing it. An example would be the style changer allowing you to make a 70's test chamber that includes the voice lines, but it seems to stick with other test chamber styles.

After solving this I watched some other videos of it and the videos have a Cave Johnson bit at the start. But when I played it there was nothing. Is something wrong with my game because I've noticed that lately.

Loved this! Reminded me of a step in someone's map long ago.

Very good! Unusual use of accelerating gel!

I had to start with a fun map from a strong map maker. @ :25 https://www.youtube.com/watch?v=DwD8Z4bbo24

Short and Sweet - thanks for making!

it's cool and fun!

Good fun. Took some thought to solve.

Fun map that needed some thought to solve. Thanks.

@Eisenmonoxid........No, that was not the intended solution.

Just one question: Is it planned that you can put the second in an endless loop where it falls through the blocked portal surface? I cleared the map that way but do not think it was the intended solution,

Slick!

Rzadko widzę pomysł z wykorzystaniem farb na kostkach, bardzo fajna komora

Thanks to everyone for playing.

ТЫ ГЕНИЙ!!!!

I'm glad I didn't look up the play-through for this one! So ruddy clever!!

Here's mine: Lost (Part 1)

In fact, the cube must reach a speed high enough to pass through the grid.

@Phil......I guess there's not much we can do about that glitch. LOL. And I thought the fizzler was far enough away.

That was great. Now I gotta go make a map and emulate your puzzle. Slick.

Nice. The gel on the second cube is not needed as it passes through the grid! https://www.youtube.com/watch?v=fASgfzDB9XE

Oh, damn, I think I threw my back out!
That was a really clever one - the way you put together the interaction of the different elements.
The tip of my hat to you, sir.

excellent chamber, first one I had to look up the solution for. but once i got it, it makes sense. Nice way to bring another dimension into the gameplay with the gels. Thank you for the chamber.

@PeterLucas.......I watched the video. LOL. It just made it by an inch. Thanks for playing.

And thanks everyone else for playing. And a happy new years to all. Maybe a better year for all of us.

What a brilliant map. Chat helped me in my stream today :D

Very original puzzle, good job! I had to come back to it with fresh eyes cause it's important to understand that cubes go further with orange gel on them!Spoiler text

Here's my blind playthrough: https://youtu.be/ZjE72ltOyaY

Please, try my In the Lab Series of puzzles!

@sixteen60 Oh that is old Portal 2 bug; and FYI it wasn\t part of the solution.

i litteraly discovered that the cube can fall through fences in a certain way by accident (i guess you broke the game)

It's quite rare to come across a test that uses the propulsion gel-covered cube technique, so this was a nice breath of fresh air to play

God this is brilliant! Using a gel to reduce the friction of the cube - even I would not have guessed before. Excellent work !!!

Yeah I guess you would bring that up, the in-engine programming is so simple it makes advanced JavaScript and DOM manipulation look like advanced cross-platform CLR programming by comparison. But collision modelling has nothing to do with it, you are already on safe ground on that. I can step in for that, the video makes it dead simple.

The programming or coding or scripting is something I never got into. Maybe text editing custom textures once or twice.

I just made a proof of concept chamber and it not bode well, modifying collision model to have a custom cart is the only way to go about it, that is the red outline I somehow triggered in Hammer, and that kind of play is never seen before for such reason, only the train ride as the opening to Half Life and Portal Stories: Mel. I am a programmer and I can say for sure modifying collision model is child's play for experienced Hammer user.

I'm not familiar with modifying collision on objects or models. Or importing something into PTI. I could perhaps take a non-physics cube and attach an invisible func_physbox underneath it, then sit it over a tilting surface to initiate motion to a sloped surface. But I think all surfaces would have to be wet. The hard part would be keeping the player from falling off. Physics can be unpredictable sometimes.

Actually we already could do it as a proof of concept, since player can jump onto cubes, what happens if you arrange a chamber setup to do a toboggan of about half a meter?

@Skyferret Have you considered modifying a collision model? I ran into someone showing how to do that on YouTube exporting out of Hammer and importing it to basic PTI, did not look into it further since I was looking for something else.

@Andy T....... Bowling For Buttons would have been Hazardous Infrastructure.
Now if I can just find a way for a player to ride a wet cube across the floor. Maybe like tobogganing?

Easier than expected, I remember Skyferret made a number of puzzles with this mechanic in mind; though it took me few minutes to dig that idea up. Last of this is his first recent PTI map by the name of Nock it off while I remember there was a Hammer one requiring bowling for buttons too.

Excellent thank you!

Fun! Really fun!!

Mega fun with speed gel.Thanks.

Good fun map, Enjoyed, Thank you.

@sheepdog......Thanks for including me in your play-through videos. I always like watching videos with commentary. And thanks everyone else for playing.

fun!

blind playthrough https://youtu.be/blzabkyWVGU?t=1458 Good use of elements but you don't need me to tell you that.

Nice!

I found an alternate solution maybe. But the orange gel have a portalable surface but i never use.

Fun slip-sliding away. Thanks for creating.

lul. it's very small xd
