    Hi, we have been using alembic for quite some time and testing for character animations with RTX to test its viability, especially with the recent updates to RTX in beta.

    There does not seem to be the alembic material remapper anywhere anymore and the old script does not work in the newer versions.

    Is there somewhere I can find a new one, or is Unity planning on an update to the alembic material remapper in the near future?

    Hey !
    This version of the material remapper is indeed not supported anymore.
    That said, we are working on implementing a more user-friendly solution for this issue. So stay tuned.In the meantime, we fixed the obsolete calls so you can use the old Material Remapper.
    To use it, edit your manifest.json to replace the com.unity.film-tv.toolbox line by this one :
    Code (csharp):
    1. "com.unity.film-tv.toolbox": "https://github.com/Unity-Technologies/film-tv-toolbox.git?path=com.unity.film-tv.toolbox#dev"
    Thanks ! (edited)

    When you render out your Alembic animation, do you get proper motion vectors for motion blur? If so, how did you do it? Was it a Motion Vector material that gave you proper motion blur?

    In HDRP you need to enable the "Additional Velocity pass" option in the material. If you use neweish alembic package versions, these params are automatically set with the default material when importing.
