Water foam texture?

[saindd]

Is the default water foam effect controlled by a texture or a particle effect? Would it be possible to replace it with an animated particle effect, using an atlas? Something like this.

There is a foam.dds so it is a texture.

You would need too many particles to cover all the water, they are just used when objects enter the water like the player.

Not out of the box because it only loads a diffuse map for the foam. It's not a material so you can use for example a image sequence animation. You'll need to change some code for that.

Further doesn't T3D's image sequence animation make use of a square atlas map but a strip of images (horizontal). You can read about it here:

Can sequence animations be used with particles? As for the foam, i'm not referring to the one that appears when the player hits the water, but also the one when water touches the terrain (e.g: beach).

Particles work with materials, so yes, that should be possible. You would really want to test it thoroughly though, I can imagine giving it a performance hit.

Foam appears where the water touches the terrain. If the player hits the water, you may see bubbles and splashes; those are defined in the player datablock and are particles.

In T3D, how difficult it is to change a simple diffuse texture into a material?

I mean... setTexture accepts a material instance, maybe?

I think the Pacific Demo has some kind of wave foam by placing decals with transparency & animation near the terrain. But if you want animated foam on the water without particles you could use a flat mesh with sequence animation material as previously suggested.

Nah, just cranks a few values up like so: http://imgur.com/a/z0Dzw fars an animation goes... not stock. though I'll note there are bits and bobs of the material features laying around to turn a horizontal strip into a frame by frame flipbook as it were.

I found a modified water shader i was experimenting in the past which adds a second foam layer to water. It has the default fields for direction and speed and I think it's easy to add sequence animation or at least fade it in-out. About the shoreline foam maybe we could do something similar but i really think this is beyond my skills :(

Any ideas when the Pacific Demo will be released? :)

[marauder2k9]

are u looking for foam around the edges or white caps on waves?

[saindd]

Just edges. I'm actually planning to write an animated material and use that, instead of a static texture.
