Goal
Particles density produced by Texture Image Sequences such as black and white.
Current Situation
Unreliable Failed results.
Question
Below particles correspond to Black and White, if I take manual intervention by clicking say ramp on .... ramp off repeatedly, the usual incantations. I have never achieved a successful render of an image sequence. Single Image I can achieve as in the below pic.
Has anyone achieved reliable results with the above goal and if so how?
