Hi all,
I've been encountering what appears to be a bug in VC Optical Flares, and was wondering if anyone else could replicate it to confirm whether it's specific to my setup, as Video Copilot haven't heard of this problem before.
If I set up a comp with Optical Flares on a layer, set it to track 3D lights, and create a light with the following expression applied to Intensity (to achieve a random strobing effect), AE becomes very unresponsive, with me having to wait 20-30 seconds for it to stabilise, and "(Not Responding)" appearing in the title bar.
Other expressions don't cause a problem with Optical Flares (eg. Wiggle), so there must be something specific to this expression that OF doesn't like.
Can anybody else replicate the problem? If so, could you report AE version and graphics card model to see if we have something in common? (I'm using AE CS6 on Win 7 with GTX 670)
Any help much to pin down the problem much appreciated.
Phil
EXPRESSION:
minSeg = 0.5; //minimum interval (must be > 0)
maxSeg = 2.5; //maximum interval (must be > minSeg)
minFlicker = 0.04; //must be less than minSeg
maxFlicker = 0.04; // must be less than minSeg
segStartTime = 0; //initial conditions
segEndTime = 0;
i = 1;
while (time >= segEndTime){
i += 1;
seedRandom(i,true);
segStartTime = segEndTime;
segEndTime = segEndTime + random(minSeg,maxSeg);
}
flickerDur = random(minFlicker,maxFlicker);
seedRandom(1,false);
if (time > segEndTime - flickerDur) 100 else 0
EXPRESSION ENDS
