After using the fluid dynamics i wanted tot try something a bit different and perhaps more suited to games. Using nDynamics i made an emitter, and told it to decrease the size of the particles the longer they were alive. It certainly doesn't look as impressive as using the fluid dynamics but it is so much faster to simulate that i may look for a way to incorporate it into my project.
After that i made a simple torch model with two parts, and made a fluid container using the head of the torch as an emitter. Using the auto resize option for the container i animated the torch moving from the upper left to the lower right, similar to what i will have to do in the final piece.
I encountered a few problems with this method, using the fall off shape for the fluid container for instance. Because the fall off shape seems to be applied to the container as a whole rather than from the emitter, if the emitter moves to the edges of the container the flame starts to disappear at the bottom.
As the flame moved it also left a trail behind, which isn't really what fire does, unless it is moving at a ridiculous speed and with a liquid fuel.
Next ill start working on adding sparks to the flame, and making the flame more realistically shaped as it moves.
