I thought this node was awesome until I tried to render in movie render queue, turns out it doesn’t work when movie rendering, seems to work ok in runtime though when the sequencer is playing.
If anyone knows how to get it working in MRQ please let me know!
My work around is to create a variable called ‘frame’ and keyframe that in the sequencer, making sure it’s set to linear interpolation, after that you just add a keyframe value of ‘0’ at frame 0 and match the last keyframe value to the last frame number.
