Problem baking textures from alembic animation

In the past I've had success with baking textures from alembic animations, but suddenly I have a project that bakes only the first frame...all the rest are black. Anyone have any ideas as to why that might happen? UVs appear to be good and non-overlapping.

Animations were originally OBJ sequences from Marvelous Designer, then brought into DAZ Studio and exported from there as Alembic within an ORBX package.

I should've mentioned: I'm using Commercial Release 3.07 of Standalone.

Could you share an ORBX that we can use to reproduce this issue?

Thank you for reporting and apologies for the inconveniences.

Sure thing. Here's a link:
https://drive.google.com/file/d/0B-y1z8vgPDdfbG5ScmY1WHMzQm8/view?usp=sharing

This file is identical to the .OCS file exported by the DAZ Studio plugin (latest stable version: 3.6.4.34), except that I've added a "Baking Render" render target with a baking camera.
The first frame of animation bakes just fine, but all subsequent frames are null.

I've noticed that if I change enough import settings on the alembic file (i.e., "Subdivide all meshes" on then off) I can sometimes "break" the animation and then the other frames will bake, but the animation is gone.

Thanks for taking a look.

I tried a new export from Marvelous Designer and started fresh...now the problem has gone away! Maybe there was just a problem with the original Marvelous Designer file.

Thanks for the heads up, I'll take a look to make sure this is not a bug anyway and get back to you.

Actually in the latest 3.07 moving geometry was not used for baking, this will be fixed in a new build we'll release as soon as possible.

Thank you for reporting this.
