This file contains a series of dynamic simulations to illustrate how one may perform some simple particle fluid work, and have voxel fluid fire spread from one object to another. The fire works in a way where two fire objects share a single smoke container and so are able to share temperature information so that one object can ignite the other.
This file has been slightly altered from the one appearing in the gallery to help the user simulate at a faster pace. Note however that there is extensive commenting on all of the nodes found within the file, and that these changes are reflected in the commenting so that they can easily be set back to higher quality levels.
How it works:
* A voxel fire simulation spreads fire from one object to another.
* The fuel attributes were painted onto the box geometry in a way that allows the fuel to burn up.
* A secondary, independent simulation drops particle fluid liquids onto the box to emulate the look of a fuel.
* A tertiary, independent simulation ignites flames on the ground in a painted area.
* Takes are used in this file for easy render passes.
* One thing that is important to note, is that lights that are lighting volumes must have motion blurred shadows turned off to correctly render motion blurred volumes.
