Here's the situation. I received an alembic file with animated car. There's no deformation, only simple translation of geometry. Cars geo weighs about 900mb and whole alembic file with 40 frames of animation is not much more than that. Now, it's time to render the animation.
As far as I know, I need to convert animation to USD. I've imported the alembic using sop_import, set save path and appended usd_rop. Because of memory limitations, I've turned on "flush data after each frame" on usd_rop. And I've ended up with unnecessarily huge file, because flushing data means that all geo gets duplicated every frame. There must be something I'm doing wrong here. I can't imagine dealing with 1000 frames of this kind of animation. What's the correct way of approaching this situation? Can I split alembic into one large geometry file and small animation file?
This is my first week with Karma and second with Houdini in general, so have patience, please.
