Oh, I almost forgot the thorniest thing I am trying to understand ... In the game I am using particle effects for things like vapor trails, explosions, smoke, etc. They seem to have their own relationship with time, and I do not know that they are "rewindable". Lets say that I am in the middle of an explosion and I want to replay that explosion, but not from the very beginning, perhaps from somewhere in the middle. Is there a way to rewind the time and play the particle effect from a given time, or do I need to somehow start a new effect over and fast-forward it to the appropriate time?
Hope that makes some kind of sense, -- Rick On Mon, Dec 29, 2008 at 8:33 PM, <rpin...@gmail.com> wrote: > Hello all, > > I am wondering about the best way to record some aspect of a scene that is > playing from a game.
