probmlem with importing materials

[hamidbarca]

Hi
i export my deformable mesh animation as a alembic file from c4d to keyshot but when i import it there is no material that i'd applied to my geometry.
when i export animation with keyshot plug-in,everything is OK but i have this problem with deformable mesh animation and alembic files
also i can import alembic file into keyshot 7.1 but not keyshot 8
i'd appreciate it if anyone answers that.thanks
