i'm working on a scene where i need footsteps to appear on a snow surface (2 displacement maps, one still noise for snow, one image sequence for the footsteps).
when i have just the image sequence as the displacement map, everything works fine, however, when i use the layer function to overlay 2 maps, it seems to ignore the animation of the image sequence.
did anyone had a similar problem and/or knows any workarounds? would love to hear them

please see attached test scene + file.
thanks,
Misha.
