System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 535.98

Blender Version
Broken: version: 4.0.0 Alpha, branch: main, commit date: 2023-06-09 10:15, hash: c70a1595efce
Worked: N/A.

Short description of error
After adding Transform Cache, and selecting *.abc file, Object Path is showing correctly end path of Alembic, but animation / particles are not appearing.

Tested on build from blenderartists.org (link) and there importing poincloud is working correctly - it's even have more attributes.

Is there a way to include that build fixes to newer version of Blender?

ps. importing Alembic as Mesh is loosing information about attributes:

Hi, please, no use third party builds as Worked versions.

Hi, thanks for the report. Bit confused about the the issue you've reported.
Is this report about some missing attibutes in spreadsheet? or missing animation on point cloud object?

@mod_moder Hi! Sorry, will remember for future.

@PratikPB2123 Hello! :)
Actually both of them.
I've started this thread in wrong aspect - I was trying to use Transform Constraint in PointCloud from Beta version to import animation, but I think there should be a Modifier for that - instead of constraint.

Importing Alembic - but only points, is adding MeshSequenceCache which is having animated points, but it's missing while importing all information about attributes (like a Velocity, Color etc.).

So - the biggest issue right now is that It's not possible to import points attributes from Alembic to Blender -> GeometryNodes.
For example - it's not possible to import huge amount of particles as whitewater / sand with velocity data using alembic.

Guess so.

@kevindietrich , can you check?
