I am trying to create an animation where several instances of an object seem to grow out of another mesh, and slightly move (rotate) then disappear (scale back to 1 again).
In the dumbed-down version of this example, I would have the cube grow out of the icosphere in random sizes, rotate slightly/move, then shrink back to size 0.
I cannot seem to animate / keyframe the Particle Size data box.
After keying it on frame 1, it doesn't let me key a second size on frame 50.
I couldn't find help online or figure out why this wouldn't let me do it. Even if I click on "No" or "Keyed", and apply loc/rot/scale, it doesn't let me change the value. I actually have to go and delete the keyframe to modify the value.
Can this be done?
