Hi,

I exported an alembic cache from a huge Bifrost mesh with a velocity channel attached to it, how can I import it inside of Houdini to be able to use Motion blur ?

That would help me a lot, Thanks!

I don't think the Alembic file format supports transfer of attributes from any package. Please correct me if I am wrong?

What you can do is simply drop down a Trail Sop after you unpack the Alembic and set it to computer velocity.

Thank you Enivob! A shot will be given to this solution! ( After a lot of research it's true that the Abc format doesnt supports transfer of attributes from package to package )

Actually from Houdini to Maya, we always transferred velocity as vertex color attrib, and Arnold can render that.
Only thing is that Maya is super sensitive to geometry, so it takes a couple of tries while you are not getting some error message or warning in maya. Also uv is an attribute too.
