# Controlling smoke/fire emision amount

It is possible to animate the emission of the smoke in smoke sim? I tried to insert keyframes in the fuelAmmount propierty in the flow object but it didn't work. Thanks.

• Could you please add a screenshot of the settings, I couldn't find the fuelAmmount property. – stacker Feb 28 '14 at 18:42
• @stacker I think the OP means Flame Rate (it's called fuel_amount in the api) However, keyframing it works fine for me.. – gandalf3 Feb 28 '14 at 20:20
• And using a pure fire emitter, do you think it is a bug? – Hikaru Ai Mar 1 '14 at 1:16
