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!
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.
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.
looks great Ulco!
Image two foreground is really great now! Amazing! Do more!!! The back ground though looks flat to me.
Thanks for the smoke Ulco 8)
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.
It's impressive, no matter what has been forgotten.
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 :D
I've been wondering how to make those volcanic plumes. Making a localized cloud with a large depth doesn't seem to do it, I just get a round cloud no matter the depth.
Use a quite soft circular simple shape (position in terrain, not final position or it won't warp) that is warped X and Z (and perhaps a little Y) wise. Use that to blend your billowed cloud fractal and play with the fractal specs to get it right. I made two colors with two cloud fractals on two cloud bases.
is good.

OK, I seem to have gotten a start, but I'm not sure I'm tweaking the right stuff. Any chance you could post a TGD, TGC or just screen pics of the right nodes so I can compare?

Hi Ulco,
Looking good :-). This sort of thing is a big benefit of the node network. The basic idea is very like the Lava from WaterWorks for v0.9, which was really quite a simple effect, but instead you can implement this in the node network without it needing to be done in a plugin. And it's looking much better :-).
Does it have any luminosity? A bit of that could be effective.
Regards,
Jo

Thank you
Thanks, Jo. Yes, it does have luminosity. Three layers (red basic and 2x orange, blended by 2 voronoi scales near the down ends, where the lava cools and the black crust appears). This might be 'cool' if I'd make some better flow maps in World Machine, as this just drawn in PS, and the terrain acts upon that. I couldn't have done his without working in the node network.
I changed the overall appearance to a more frightening one by adding an orange-brown cloud and leaving out shadows from surfaces. Low res for now.
That last one is looking really good! Nice work.

You have achieved he frightening look. This last render is the best yet in this thread.
Very, very well done. The clincher is the lava - glowing red hot underneath with a darker, fractured crust forming on top of the flow
Image 2 on page one still has the best foreground! But everything else in the last image^^ Is much better now! Really looking great Ulco.
You must do a simple animation test or two, to see what can be done to make the lava move. If you can get it to look even close to real, you could use it as an animated matte for the back ground of some video.
Since you like historical subject mater, maybe an image or two of Pompeii?
http://upload.wikimedia.org/wikipedia/commons/thumb/5/5c/Pompeii_the_last_day_1.jpg/220px-Pompeii_the_last_day_1.jpg
Animation of the lava is hardly possible as it is a mask, and it won't roll downcrater following deepest areas.... well.... maybe still.... if I could blend that mask by another widening mask, which is animated... still hard, but maybe possible.
I like image 2 because the crust is so varied. I used another warper in there. Maybe I'll make a combination, and I might get the chance to have this properly animated as part of another venue ;)
I do think to reduce the shine on the crust and make it more crust like.
The lava looks good Ulco. Animating could be hard as you said but would be interesting to see really !
Thanks for the file :)
Here's a next test without all the smoke. Still some things to take care of.
I tried to upload a test to vimeo, but it doesn't appear. Probably the wrong codec. Animating worked fine, by the way.
Hope to see it soon!
I hope it'll work this time. In 30 minutes time it should be ready..... https://vimeo.com/42483010 (https://vimeo.com/42483010)
It certainly looks interesting Ulco :)
Maybe 2-3 times the speed would look better. But i liked the kind of flow.
The sound of the video is problematic Ulco but doesn't matter for me.
It is hardly interesting to animate lava flow, as it goes very slow in reality, and will use up a lot of frames. Speeding it up will make it crazy. Yeah, the sound is horrible after they rewrote the avi.
This is the kind you say probably Ulco:

But...

Here says it can be as fast as 40 miles per hour:

It depends on which kind of lava you want to animate of course .
It is interesting for me but if you don't find it interesting don't do it Ulco ;)
Thanks, Kadri. Very enlightening. So I can make a believable eruption/flow after all with my spare means.... that is; not too long but moving at the same time.
I think its ok for a close up, but very good for a far shot. I hope you will keep working on this when you have time. It looks like the method you are figuring out could apply to other things as well, mud slides, for example.
I've set up a new animation of 500 frames, so I hope I'll get it done some day. Cam moving down towards the crater, while the lava is streaming down. Last bit is close up. I am now trying to get hot lava spewing from the crater, instead of the fat clouds (which I can't animate to boil up believably). Possibly by means of an red/orange chunky cloud, which should move up and down irregularly ???
I want to exchange the simple hand drawn lava flow map by a more decent one, so I have made a crater in WorldMachine, with some nice eroded gullies. But can anyone tell me how I can get the lowest areas of these gullies to act as a flow map, in other words what should I do in WorldMachine to get that flow map? I have now saved both flow and deposition maps, but although they do give some nice lines streaming down, they do not follow the lowest areas.
Screenshot shows some lava lines, but I'd prefer them in the real dips. And here's the tmd file as well.
Crashes my WM, which version are you using? I'm using 2.1, maybe I need 2.3 ...
Richard
Sorry about that. I have 2.2. Don't know if I can save in lower version.
still rendering?
Well, I need to have some good looking streams of lava first. It also renders quite slow with all the smoke, so I won't do that without proper maps. And as I jump from here to there, it has been lying around....
Fantastic project (I admire all the hard work you've done since but there is something about your second image (ie the first re-work) that just does-it for me)
Love the animation too
