I have image sequence that I want to use to control particle spawn area. Image sequence is black and white mask in nature. It depicts a moving disc:
When I try to use the same sequence to control particle spawn with the "Density" controller, I get very wacky results. They seem fine in viewport as you will se in the gif below, but in render results are wrong.
Render of the same scene, does not look like a viewport result
Here I made a gif of my process (20mb): https://drive.google.com/file/d/1-GA9eF6biSXK4Nv2on2QecZgIRAdwrOS/view?usp=sharing
So how do I control particle spawn with the image sequence the right way?
Unfortunately blender can't pack image sequences in to file, so i put my blend file and image sequence here: (1.3mb total) https://drive.google.com/drive/folders/1CcxzUDwEFGFghC-nYHWwr8zidshfLb7y?usp=sharing
