So I have my fire, and I can't seem to turn it down. The size of the fire goes up by the size of the surface area of the surface emitter. I dont want to shrink my emitter. I need the fire to get smaller though. Which channel will help me shorten the flames height. I've tried changing so many things. I feel maybe I just missed noticing the right one. Thanks everyone.

ps. sorry i'm learning by example here. this may be a dumb question :)

Suggest try tweaking your boeyancy?!?

Turning density or temperature buoyancy down turns my orange fire black to the very dark tip of incandescence. :(

***yeah still working on it, i just want a shorter fire!

the fires a bit of a hack, in that it disapears at the top b/c it exits the fluid container, so if you reduce the hight of the overall container the flames will get shorter... well in a sence anyway. I sugest looking at my firent Peter Shipkovs fire set up, it's one of the best readally available fire setups.

It takes whats good about the maya fire set up and makes it better. the maya default that you are useing uses the edge of the fluid to look like fire, so when it's a torus you see more edges, so if you make a lot of small object to emit from you get more of those edges that gives the fire impression.

Or better yet, as destruct007 stated, use multiple toruses's... ah torii

hi ,
Certainly you have already try , but you can increase the density disspation , in the fluid emitter increase the fluid Dropoff . And so , you can increase the resolution of your fluid container , all simulation parameters works in function of the voxels sizes.
hope that help you ...
