I tried increasing the life and basically what happened is that it increased the intensity (when using any of the x-ray emitters) but did not to the length of the clip.
I did notice this though, when I went to see the life properties….. that you can change the ‘vertical line’ by moving it up and down….. however, I noticied a horizonal line that was stuck at 120 (x-axis) and could not be moved at all. I wonder if that has anything to do with the length at all? I increased the initial frame rate of the project from 120 to 200…. when i did the horizontal line that was originally stuck at 120 had moved to 200….. but the same problems kept on happening (clip would stop at 2 seconds and repeat, the intensity would increase but thats it).
