Exactly as the title says.

Some nice textures and techniques in there. The yellow in the lower lava texture could do with being more orange than green imo. It might work with using an "add colour" with it to get some white hotspots.

the smoke plume looks very good

but the lava flows dont look as realistic as they would in real life, doesnt have that "flowing" look.

but great job anyways.

I'll see what I can do. I threw in some voronoi to get hot cracks, but initially only had warped ridges, which might have been better. I put more black in the lower end to get cooling rock.

I think rather than cutting a channel, the lava would be a flowing lump, so rather than a negative displacment on your flows, make it positive maybe.

Ah nice. I'll see if I can do that. I do have some + displacement in the flows, but apparently not near enough.

Nice use of the old SSShader!

Dune · May 11, 2012, 03:01:04 AM

No SSshader this time, but it is procedural, and could be done with a set of SSshaders as well. What I need to find out (again) is how to get this bulging over its sides idea. Like how fake stones work, but then from a soft mask. I don't know if redirect works in either direction. So, if you take a round SSshader as a basic mask, and make it into a mushroom, without using height restriction! Back to the drawing table.....
You're making this hard, Jon

EDIT: Got it.

Like this Ulco. Keep going for sure!

Also, would you mind sharing the details for the foreground smoke. I know thats probably the simplest thing you did here, but it interests me anyway.

Dune · May 11, 2012, 09:57:34 AM

This is about what I can do. Only forgot to change the dust distribution, so it's all a bit reflective now. And this is the smoke, TheBadger... nothing really.

FrankB · May 11, 2012, 11:49:39 AM

looks great Ulco!

TheBadger · May 12, 2012, 07:56:23 PM

Image two foreground is really great now! Amazing! Do more!!! The back ground though looks flat to me.
Thanks for the smoke Ulco

Another version. This time I forgot to eliminate the voronoi in the luminosity at the higher end, and to raise the lava streams there. So, it still needs work.

Henry Blewer · May 13, 2012, 08:55:34 AM

It's impressive, no matter what has been forgotten.

Dune · May 14, 2012, 01:38:20 AM

Different setup, but low quality renders for the time being. One with a simple painted (PS) mask, the second is procedural, but the lines are ... well, just lines.

And to celebrate this I have let a lot of glowing balloons up
