Optical flow for Niagara smoke #55

Open fezsid opened 1 year ago

fezsid commented 1 year ago

Hi, Can you please confirm if EasySynth can generate optical flow for 3D Niagara smoke particles in UE5? If not, is there any workaround? I am trying to generate an optical flow simulated dataset of smoke plumes from a drone's perspective in a forest environment.

Hi @fezsid,

It seems that such a use case would be too optimistic. Due to UE limitations, optical flow currently only works correctly when the camera is moving, but the whole scene is stationary. The most recent UE releases may have changed something, so I will give it a try for the next EasySynth version.

Thank you! Please let me know if I can contribute in any way to achieve this task.
