For my upcoming game “Surreal System” (http://www.indiedb.com/games/surreal-system) I wan’t to start the game with an opening cinematic. Blender is used for everything in the game except the engine itself, and I want to use blender for the cutscenes as well, but there is a problem!! D: Blender has a great smoke sim but I am having trouble setting it up so that the fire will start in the bottom left corner of the Zepplin and spread to the top right. Any ideas on how to achieve this???
P.S: All assets in-game are created in Blender and all textures in Gimp. I will post some WIP shots of the opening scene soon as well! 
Happy Blending!
