>> Smoky Skull With AfterBurn <<
-
ALi 608 posts19 Aug 2007Hi Friends. Long time no see.
I have a problem here. I wanted to build a scene when smoke shapes a skull. I need this for our recent project.
My idea was to set a find target and speed by surface to get what I need. and it works. but I want to use afterburn to improve it. cuz particles does not look pretty good by themselves.
In order to shape the skull correctly I have to made a lot of particles and it mades afterburn rendertimes very long. also I can't achieve the details I want with it.
So I'll be very thankful if you have some good idea or a link to a useful tutorial. -
24 Aug 2007I can't help much on this - the only thing I can suggest is asking our resident afterburn guru...
Cam?...

ALi 608 posts24 Aug 2007Yes. I think so.
..knock knock! Hello! you ther Cam?

24 Aug 2007I dont think afterburn will be that much use here. The trick I found with ab, is to use less particles, but bigger puff sizes, so they blend together. I can control the detail of what I do with the afterburn noise settings, but since you have to form a specific shape, im not sure afterburn will be best option. As you said, it increases rendertimes dramatically, and having the puffyness can sometimes look kinda crep.
having said that, something you might want to try if its just simple smoke, is to use the octane shader on any number of particles, and throw a decent amount of mblur on em to hide that puffmonster look and make it flow. Octane shouldnt be too much of a strain even if ur working with a very large amount of particles. Only trouble with that is you cant control as much details inside the afterburn as you'd like, but you can through number of particles.
Tis the choice I make, particle count and location to control details - use octane, afterburn to control details - use the main shader. -
ALi 608 posts25 Aug 2007Thanks Cameron. will try if it works.

ALi 608 posts11 Sep 2007I couldn't made it through afterburn. so I have an idea to make it with Fume-fx. This time I have problem with amount of RAM. but think with an optimized settings I can do it. any idea men?

12 Sep 2007to me, this whole problem sounds much more like a particle problem than a afterburn/fume problem. If you can get the particle motion to be smoky, then form into a skull, you could use regular materials or afterburn to render it with a smoke shader and it would look fine. It's getting that natural smoke motion that would be tricky, no?

ALi 608 posts17 Sep 2007Thanks for reply hype. but that's not the problem. I worked on particles and it's looks pretty cool. but in order to get more detail I had to add about 5000 particles and when I use afterburn with them it's much.. argh
rendertimes grow dramaticaly long. and also the result are not so fine. but along fume-fx it looks better. though with 3GB of ram max crashes.
here is the particles I made with pflow if you want to take a look. -
JeNgA 1 posts18 Sep 2007hello there i am new to this forum i actually got here cuz i am a fan of Tyson. OK, first of all you will always need lots particles for this kind of job to get done now u could also do this by chunks render some particles and then render some more and so on and then comp them together or you can try and bake them bake there animation and then do another pass and bake that one till you have enough particles, other than that you will have to use millions of particles to get this to behave the way you want and for that you are going to need atleast 8gb RAM (12gb Ram recommended) on a dual or quad processors (64bit recommended)
heh expensive ain't it
. Another solution might be thinking particles which use another method for there particles that let's one use big amounts of particles with less hardware and memory. well best of luck and if u get this done please post it up so that we can learn

ALi 608 posts18 Sep 2007Thank you mate. sure I will aware you as I get a good solution. I'm going to test thinking particles.

ALi 608 posts12 Oct 2007I just wanted you to know.
Finally we used Fume-FX to do the stuff. I can't post the result. But here is what we did.
We used two fume-fx solutions. one object based to shape the skull and one simple emitter to shape the whole smoke. Set the buyancy of object based emitter about zero and added more details to it. The the result was acceptable though the render times was not much long.
I will ask my director if I could post the result for you to see.
