Laser-specfic Alembic export

[lyallmarcus]

Alembic feels like it could be a great format for saving laser cues.
You can play it back to timecode, it’s a 3d format you can import into other software.
It’s an open format. It’s GPU-accelerated in TD.
Currently TD doesn’t play back the colour properly (see below).
But while improving this, could various laser-based attributes be saved in the alembic to aid laser drawing? Corner holds, etc?
Laser CHOP could pick these up when a POP is used.

A chance here to make Alembic a defacto laser standard!

Adding color to Alembic Out file

Exploring exporting POPS as Alembic through Alembic Out node. Really useful for creating laser cues and LED simulations. The issue I now have is that when I export my object, I can reimport it, but the colour appears to be playing back slowly from an Alembic POP. It’s as if the position oinfo is playing bnack realtime, but the colour info at 1fps. There’s also a knack to adding colour to Alembic exports. I was trying to add a color attribute. Was getting lots of errors because you to need to…

The Alembic Out POP supports exporting of custom attributes, including those accepted by the Laser CHOP (ie. LasCornerHoldAdd and LasCornerHoldLookupFactor). Are you having issues with exporting either of those?
