I have made a rain simulation using expresso, but it is only visible for about 200 frames of the 3000 frame project. Now i've added the simulation, the play back is unbearably slow. In the expression i've managed to make sure the animation doesn't start till frame 1000, but i can't figure out how to get it to stop. I basically want it to not be there at all until frame 1000 and then be gone again from frame 1200. How do i do that?
the simplest way is to keyframe the PStorm On value at frame 1000 and frame 1200 rather than Comparing if it's at frame 1000 or not - it is possible to test if you are in-between frame 1000 and frame 1200 but it's so easy to keyframe the On to be off-on-off (pass a Constant into the On port)
