Wow, how was it done?

It's just an animated texture. NW wad has a few textures like this.

You are wrong. And what is NW?

That is a ton of scrolling textures, but it just looks so go! nice work!
NW? I think he meant NS.

No, he meant Nightwatch, a mod that died many years ago from a very very dumb decision.

You are right. Basically it's just 2 textures going in opposite directions, so not really a ton. I also used pyramid technique instead of 1 unit wall, so you can't see it as a layer on top. It took a bit of experimenting and it's still not final. With a bit of time you can make it physically correct and look a lot more realistic.

Firearms did this 9-10 years ago.

Will you be posting a tutorial, or an rmf?

It's too simple. You can do it yourself lazy bastards.

By the way, the underwater sun rays were also done with a grid of scrolling func_conveyors.

Not really sure what i'm looking at but i'm sure it's awesome (i subscribed ;)). Is this like scrolling textures used for rain or fog?

I feel like i should know this , but what is the 'pyramid technique'
Posted 13 years ago2011-08-01 00:25:41 UTC
Post #297227
When you clip a 1-unit deep brush from its centre to all 4 of its edges, creating a seemingly flat surface which is actually raised by 1 unit in the middle.
Posted 13 years ago2011-08-01 07:45:44 UTC
Post #297236
Correct.
Posted 13 years ago2011-08-01 08:13:50 UTC
Post #297237
couldn't you just leave it all 1-unit thick and null the unused faces? I too am having trouble visualizing this, and feel like i'm trying to over-complicate the idea?
Posted 13 years ago2011-08-01 08:35:35 UTC
Post #297240
If you look at the edges of the walls, you would be able to see that there's a gap between the wall and the effect. Using a pyramid stops that from happening.

Post #297241
oh nice! do you still null the "pyramid" parts or do they have the scrolling texture as well? I feel this would be a neat example map. =)

Post #297245
The bottom of the pyramid is NULL because it's facing the wall.

Post #297250
I still have no idea how did you make this. Wouldn't it be easier to post an example RMF?

2 brushes on each surface you want to be hit by the caustics. Use the pyramid technique to "blend" these brushes into the surface they're on. Create a texture on a matte black background and set it to scroll. Texture the brushes in this, setting their rendermode to additive and FX amount to 255 (this will hide the black parts of the texture).
Set one of the brushes to scroll the texture in the opposite direction from the other.
That's my theory.

And it's absolutely correct. However it's not that easy to get a texture which will look as good as mine.

Well there are tiling caustic generators available, so if you spent hours perfecting yours you probably could have done it in 5 mins, sorry :3

I used a caustics generator to make a portal 2 style emancipation grid for my crappy "portal 2 in sven coop" map

Thanks Daubster. Mine is generated too, but that's not what I mean. I had to try a lot of different types of water caustics textures to find one which looks good because most of them looked terrible. And I find the best textures those which are blurry and the worst which are sharp and detailed.

I've seen this done before in a mod. Nice work! I was looking at water the other day and noticed the reflection and how beautiful it was and this mimics it great. I'll have a try at it with my nice water texture.
