Yes I am using Crate. I have also tried setting up the ICE tree described for importing custom attributes in their docs:
https://docs.google.com/document/d/1SEZhypDrmFRO_rSmfuv7QCNzs7jVSHG_KeUauizcS9o/edit But I get values 0,0,0 for the v attribute, and no motionblur, so a bit lost regarding how to get it working.
