View Full Version : Realistic smoke simulation in AE

07-01-2008, 09:16 AM

here is a simple test movie of rising smoke done in 2 minutes + rendering time completely in After Effects by a bloody beginner (me):


The simulation and rendering is done with Incense, an After Effects plug-in i'm developing.

Looks really good! Is it going to be commercial plugin?

Interesting... 3D CFD in AE.

ssalo: yes.

The above test sequence renders at about 3-4 times the duration of the movie on a GeForce 8800gtx. Previewing is possible at real-time frame rates and depending on the complexity and resolution of the scene at least at interactive rates (~10fps). This allows for a lot more intuitive editing of such simulations than usual.

Very interesting indeed, looks very very good. Do you know if your specification of AE plugin is compatible with AE compatible hosts? Like Combustion and most notably Fusion?

Totally interested ! Registered just awaiting the confirmation email...

Are you going to do fire or water as well?

Looks promising. Would like to test, alas no time atm. Hope to see more soon.

suztv: fire yes, water maybe in a somewhat more distant future...

Nice result !

Is hard to code plug-ins for after effects (not the effect itself) ?

AE is very old and has grown a lot over the years. The software design is not very elegant and the documentation does not compensate for that. On the other hand it allows you to do a lot, i.e. most of the time, there is some way to get things hacked in.
Considering that the portion of the code that has to deal with AE may be very low (<5% in Incense), the API isn't really that important, though.
But if you can, write OpenFX plug-ins instead ;)

After voxels, fluids, particles, expressions, questionable self shadowing in maya and huge rendertimes....I just registered.

Dead keen.

The next development preview is available.
GeForce cards are not required anymore.

Here is another simple example:

You can get the plug-in at the forum:
