I think it looks very unrealistic actually. If you look at 6:22 in the video, you’ll see a huuuuge stream of gel speeding towards the floor… and when it hits the floor, in huge amounts at high velocity, only a really small puddle forms. Heck, at the rate the gel is emerging from that tube I’d expect the whole floor to be covered in the blue goo in less than a minute.

Another example is at 8:20. There comes enough orange goo out of the tube to paint half of the room orange, but when it’s all dropped in one place on a wee little ledge - again - only a small puddle forms.

Am I the only one who thinks the gel - or more precise, the effect it has - looks incredibly unrealistic? I think it would look a lot better if the gel didn’t come out in such insane amounts. Either that, or if the game had some real fluid physics. :slight_smile:

maybe the fluid has a low density?
but anyway, I was talking about the fluid effect, not the decals.

#23

Should I go there? Köln is 190km away from here.

Only special people (journalists) get invite to see Portal 2 videos.

But if you want to see the other games, you should go.

#25

It’s not supposed to be realistic, it’s supposed to look cool. Besides, implementing actual fluid physics would bog down the system too much and would only complicate gameplay.

Functionality over realism ftw.

#26

btw, try fluid simulation in blender, you can see there how resource intense that is and that it’s not possible to do in realtime

#27

I doubt, if this has been implemented, that it would be like Blenders. Take the tech demo Nvidia released in 08, the engine made it so that the GPU took about half of the load off for your processor, letting it render in real-time.

#28

in this techdemo the fluid was like lots of metaballs which collide with each other but with a simpler collison, without friction and rotations of the object

#29

Either way, it’s still too heavy to implement in games.

#30

Wheatly sounds dumb now.

#31

Looks like the Episode 3 team is falling behind the other Valve teams.

Oh well. This game looks good anyways.

#32

QFT, i preferrred the placeholder.

#33

Meh this game looks so good I can’t wait to see what they’re doing with Episode 3.

#34

I doubt that Portal 2 will support PhysX or DirectX 11(GPGPU).
The fluid is just a simple CPU calculated simulation.

#35

This is cool stuff.

Did you see that bridge thing that you can portal around?
Its around 9:02.

#36

Portal 2 confirmed? 09-02-2011? do you think that will be released along with ep 3 as was rumored?

#37

Things that good never happen.

#38

Projected bridges, one of the new features.

rumors are fake, mate. Valve doesn’t want such a rivalry, with releasing 2 games at once. They always release one after one.

#39

They’re already competing with Deus Ex 3 by releasing it in February.

@ video:

Also, thank god they changed the voice. This one’s funnier and a lot less annoying.

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
