I'm putting together a rather complex screen sequence that is very sensitive to timing. Objects and actions load quick enough when triggered, and so far nothing like that is affecting the timing of the sequence.
However, particles are a different story. I need rain at one point in the sequence, but turning a condition to true for the object assigned to the rain creates a noticeable pause (animations, characters, and objects stop moving.) I've tried some trickery, such as turning the rain object on at the beginning of the sequence, hiding it behind a layer, then moving it past that layer's object center once I need rain, but that apparently doesn't work for particle systems.
So, my question: Is it possible to make a particle system invisible/visible without using a condition trigger on an object?
Thanks in advance.
