I used Trapcode Particular where I used the particle emitter to spawn spheres traveling upwards that masks out the flame.
Can’t find the tutorial I followed but what I did was spawn lots of white spheres to get a basic shape, then lots of black spheres on the sides moving upwards to mask it out so it animates.
And I need to render it out to a flipbook so I later on can use it particle effects etc ingame. I want a result similar to the flames in the kung fu panda movie, where they as far as I’ve understood used this technique. I guess it’s different when you do it for movies but I assume I somehow can get a proper flipbook from it for games too
