Alembic Export


Is there any tutorial/guide/hint for the correct workflow to use when exporting to Alembic?
What I would like to do is to export only the geometry and then being able to overwrite the file in case I want to change the animation.
I have never used Alembic and I would like to be sure to use a correct workflow not to have surprises at the end

I haven't found any super solid tutorials per-se. But I have spent a bit of time digging into using it with Maya. The first step is to get a rundown on all the Export/Import options. Type AbcExport -help
AbcImport -help
In the script editor for a good little breakdown of things that aren't available just using Maya's GUI. As for overwriting the files, I guess you could, but as with lots of cache formats, overwriting something that is bring read in somewhere else can cause issues if those actions happen at the same time.
If you are looking for a way to replace existing caches in a scene, you can do this a few ways.
You can use Maya's Alembic Replace command. Select the root node of your cache and the replace command will update things with the new cache. Haven't pulled this apart in any extreme adding/removing a whole bunch of nodes between caches.
You can just change the path on the Alembic node. It won't update, as the snappy performance of the Alembic caches is supposedly connected to the fact that this file connection isn't 'Live'. But if you save your scene after updating this path and re-load then the cache will be updated correctly.
Hope that helps.
I am looking for more info to if anyone else has any thoughts.

Thanks Ben!
Didn't know about the hidden flags. I'll let you know if I have any trouble
