Optical Flow TOP

When importing .tox files containing an Optical Flow TOP, you may encounter pixel formatting errors

We would recommend using Smode’s Optical Flow , or it’s ISF equivalent
for most cases.

However, if you’re in a setup where you want an Optical Flow to do specific interactions inside the .tox file :

We would first and foremost recommend using the Optical Flow component accessible from the Touchdesigner Palette (Palette/Derivative/Tools/opticalFlow)
instead of the basic Optical Flow TOP. The component’s output is of better quality, and it takes up far less GPU ressources than it’s TOP counterpart.

The OpticalFlow TOP also requires forcing specific pixel formats to function correctly. If you don’t, it should output only black when imported
into Smode.

The following workaround will make the Optical Flow TOP function correctly :

In your .tox network, place a Resolution TOP before the Optical Flow TOP.
In the Resolution TOP, go to the Common tab, and set the pixel format to 8-bit fixed (RGBA).
