It seems that my previz.tox file won’t drag into the latest touchdesigner build without crashing. It opens fine if you double click on the tox file.
Another bug with the same component:
If you change the custom parameter: Position of /previz/geo_projector1 whilst the custom parameter Uselookat is off then the render TOP doesnt update the new position of the geometry (yet it does update it’s child light and camera). If you turn on Uselookat then everything works as expected.
