Right now particles only have parameters for start and end opacity, but I want my gas particles to appear and disappear smoothly. At the moment I can only make them disappear abruptly or appear abruptly. Is there a way to get around this? Otherwise I think a “midpoint” parameter would be a useful feature to be added.
The only solution I can think of is changing the opacity of the particle emitter itself with a tween, but obviously this does not really solve the problem.
