Thanks for the tip Ho Chung Now I'm getting somewhere, but, I still have 2 issues
1. Using your scripted solution I managed to get deformation working but with the wrong timescale, basically I need to multiply Current Time by 25 to get the animation correctly. So there might be an issues here between frame<>seconds. Any way I can fix this time property using scripting? 2. I was also testing non-deforming animation (kinematics) but doesn't work with the script you provided, I guess what I'm missing is how to connect the alembic cache node to the geometry local transform Matrix. Any tip of how to do this ?
