Hi there!

I want to colorize particles from an alembic file based on an image. Something like the first picture.
But the same setup doesn't work here, seems like I can't “initialize/reanimate” the imported alembic points.

I'm fairly new to Houdini and I might ask a stupid question and there is no way to do that, anyhow.
Some help would be appreciated! Thanks!
