Tutorial of generating optical flow?

[HaiyiMei]

Brilliant work there!
I have imported the asset successfully, but I don't know how to use this preprocessing material. Can you show me how to use it to generate optical flow properly? For instance, how to detect optical flow from a single camera view with a camera actor? Thanks!

Is there a way to save RGB image and optical flow image as files simultaneously from the same view of a camera actor?

Hi just want to ask, which version of Unreal you use to import the asset? I cannot find any of the assets under the PostProcess folder using unreal 4.20.1. Thank you very much.

😂 I don't remember, it's been too long. But normally, higher version of UE is compatible with lower version assets.
