first of all I love the new animated Vray proxies.
What would make them even more amazing would be this feature:
The possibility to animate the actual frame or playing-speed (animating the offset would also work), which now isn’t animable.
Make the playback speed relative to the distance a looping proxy moves. If you have walk sequence (in place) that loops each 2 steps, you can give the step size/distance as input and the plugin calculates what proxy frames are rendered depending on the distance the proxy moves !! Then you simply move/animate the proxies position or bind them to particles. This way you can easily make crowds…(BTW this has already been requested)
