Cloth tyCache motion blur problem with vray

[tyFlow]

So I thought I could repro the issue but it turns out I was accidentally testing the wrong tyFlow version (was using tyFlow for VRay 3.6 in a max install with VRay Next). Once I used the proper tyFlow version, motion blur rendered fine both in the cache and the flow.

Can you confirm you've installed the correct tyFlow version with your VRay install?
