Hi all, 🙂

I have a simple light in the FLA attached, and I want to put it on top of a Christmas tree graphic.

The only effect I want to add to it, is that I want it to have a random alpha, sometimes tweening randomly and smoothly back and forth between anything from 100 - 75%, and sometimes flickering in a single frame between the same parameters (100 to 75%).

Can anyone tell me how this can be done?

Thanks. 🙂
