Optical Flow and Particles GPU - incorrect mapping

General TouchDesigner Discussion
1

Any Optical Flow-ParticlesGPU experts here?

My network is working properly.

The one remaining issue is that the mapping of my Optical Flow movement is not scaled correctly in my ParticleGPU component.

ie my horizontal hand movement only affects the central portion of my output.

I think this might be something to do with my Point Transform TOP or UV ramp settings.

Any suggestions appreciated!

Hi @art3mis,

have you tried the Optical Flow Size Remap parameter on the particlesGpu’s “Forces” page?

And are you using the Optical Flow TOP for this?

cheers
