How to get the smoke animation to disappear after end frame I have made an animation, which lasts from frame 1 to 3600.
Within this frame range, I have made another animation from frame 2260 to 2600.

The problem is, that this smoke animation from 2260 to 2600, does not disappear after frame 2600. It just freezes and stays as it was at frame 2600 for the rest of the animation. Instead I want it to disappear.

Do someone know how to do that using blender internal render?

Thanks for your help.
Note: this answer was posted before the OP specified the BI render engine, I am leaving it in case future viewers are using Cycles.

If you are using Cycles you can make the smoke disappear at a certain frame my simply animating its material.  To do this add a mix shader node and plug your smoke nodes into the bottom socket, leave the top socket empty.  You can then animate the mix factor on the mix shader to make the smoke disappear.



A value of 0.00 will give no smoke while a value of 1.00 will give full smoke.
