Short description of error
Save with remap relative paths option is not respected for Alembic imports. Images for example are automatically changed to relative paths with this option.
Exact steps for others to reproduce the error
Import an Alembic, save with remap relative option.

Cannot reproduce (unless I am misunderstanding something here).

You are talking about the paths in the Mesh Sequence Cache modifier and the Transform Cache constraint, right?

If I import an alembic these are set to absolute paths, if I then save the .blend [without saving before] with the Remap Relative option, these get relative paths as expected.
If I save the .blend in a different directory with the Remap Relative option, the paths get remapped as expected as well

Could you provide exact steps to reproduce the issue [uploading a .blend or .abc if neccessary]?
Also see the manual

Marking as incomplete for now...

I found more detail on the problem:

Remap relative with alembics that were exported with Blender - Works
Remap relative with mesh cache exported from Maya - Works
Remap relative with transform cache (empty, no mesh data) exported from Maya - Doesn't work, and causes other previously working mesh caches to not remap relative
TWI_CLB_0015_locator_baked_head.abc
remap test.blend

Still cannot reproduce:

I open your .blend
I open my downloaded TWI_CLB_0015_locator_baked_head.abc in the Transform Cache Constraint

 [was set to C:/Users/kakapoopie/Dropbox (The Witness)/TWI/Crews/VaughanLing/CLB_0010/Alembic/TWI_CLB_0015_locator_baked_head.abc -- thats obviously not valid on my machine, it's now somthing like /Downloads/Blender Bugtracker/54734/TWI_CLB_0015_locator_baked_head.abc]

If I save the .blend in a different directory with the Remap Relative option, the path gets remapped as expected as well
If I import TWI_CLB_0015_locator_baked_head.abc into a new file and SaveAs, path gets relative as expected

Still cannot reproduce: - I open your .blend - I open my downloaded `TWI_CLB_0015_locator_baked_head.abc` in the Transform Cache Constraint ``` [was set to C:/Users/kakapoopie/Dropbox (The Witness)/TWI/Crews/VaughanLing/CLB_0010/Alembic/TWI_CLB_0015_locator_baked_head.abc -- thats obviously not valid on my machine, it's now somthing like /Downloads/Blender Bugtracker/54734/TWI_CLB_0015_locator_baked_head.abc] ``` - If I save the .blend in a different directory with the Remap Relative option, the path gets remapped as expected as well - If I import `TWI_CLB_0015_locator_baked_head.abc` into a new file and SaveAs, path gets relative as expected

@heavypoly: could you confirm it is working as I described above?

Found another detail to the problem. Remap relative works properly if I import an alembic. If I import 2 alembics, the 2nd imported does not remap relative, while the first imported does. (These alembics are coming from Maya)

@dr.sybren, I’ll let you handle this, should be your playground :)

I still can't reproduce this in Blender master (9dab57a9f8). Also with two different Alembic files imported as two different constraints on two different objects, it just works fine. The source of the Alembic file (whether it was written by Maya or Blender) really shouldn't matter in this.

@heavypoly please test with the latest daily build from https://builder.blender.org/download/ to see if this is still an issue. If it is, please provide us with the necessary files + steps to reproduce.
