How to random alembic frame for point instance procedural. like crowd in stadium.

If your ABC archive contains an animated clip, you can access it by modifying the abcframe intrinsic on the alembic primitive in question.

That probably means transitioning to a copy-sop based packed primitive workflow instead of point instancing.

In theory, it should amount to a similar memory footprint, but in my experience there are several gotchas.

Cheers,

Hello, keyframe.

I'm very interested to hear these gotchas, if you will. Thanks.

Thanks keyframe, I will look into the detail of it.
