a nice cavern filled with lava

The mesh itself won't change, no. The ocean_water shader does kind of change the mesh (it also only works on materials that are named "ocean_water", "water_surface_calm", or "water_surface_underwater"...) but not any of the others.

Well it changes the mesh on my material named "lava_surface"

I didn't mean it doesn't work as in it does literally nothing. I meant it doesn't work as in it doesn't behave correctly.

I prefer some kind of "static" lava: too much move like the ocean is weird (specially on the corner), or can be used for a lava river, but here I think it looks better with low speed.

I use the beach_ground_normal and another diffuse texture (red). Anyway this is weird too. Couldn't find a correct texture.

What it need too is something like an "eruption" particle.

This time I used an emissiveMap for brightness, scaled the texture down, and reduced the wave amplitude. the 2 textures are here : http://ge.tt/9HPTdWE2

Also I added self.go:playSound("magma_golem_meteor_fall") instead of just playSound for the 3D effect.

I have just a weird "white blue" result when the surface is seen from under. But should we see lava from under in a mod ?

What do you think ?
PS: I will see what can be done for the eruption effect.

Now that's looking much better!

Nice; maybe a bit much on the fog part.

AndakRainor it appears that your one file may be broken as it doesn't download. The lava_dif.dds is the file that won't download.

That's odd... I re-uploaded it now it works.

I saw the problem with the ocean shader Minmay talked about. It seems after some time the waves are reduced to 0 amplitude. I don't know if the formula is good but I tried to follow the advise in the code commentary of water_surface_calm "compensate this by increasing wave amplitude to unrealistic value..." setting it to a proportion of the time parameter. So the effect seems to continue at least a lot longer now. Also reduced the fog a little and redefined the sound of explosions.
