Alembic (.abc) Export Settings

Tutorial / 06 October 2023

To export a .abc asset from Maya for use in other programs, follow these steps:

1. Ensure ABC Export and Import Plugins are Loaded:

   - Go to `Windows > Settings/Preferences > Plug-in Manager`.

   - Make sure both `AbcExport.mll` and `AbcImport.mll` are checked for "Loaded" and "Auto load". This ensures that the Alembic export and import plugins are enabled.

2. Select the Geometry to Export:

   - Choose the geometry you want to export. Make sure it's selected in the viewport.

3. Access the Alembic Export Options:

   - At the top of the Maya window, navigate to `Cache > Alembic Cache > Export Selection to Alembic...`.

4. Set General Options:

   - If you're exporting a static asset (non-moving), set "General Options" to "Current frame". This means it will export the geometry exactly as it appears in the current frame.

5. Configure Advanced Options:

   - Ensure the following settings are enabled under "Advanced Options":

     [x] Strip Namespaces: Removes any namespaces from the exported geometry. Namespaces are a way to organize objects in Maya, but they might not be supported in other programs.

     [x] UV Write: Ensures that UV (texture) coordinates are exported along with the geometry. This is essential for maintaining textures in other programs.

     [x] World Space: Exports the geometry in world coordinates, which is typically what you want when transferring assets between different software.

     [x] Write UV Sets: This ensures that all UV sets are exported. This is critical if you have multiple sets of texture coordinates.

     [x] Filter Euler Rotations: Helps to avoid gimbal lock issues with rotations. This can be important for maintaining correct orientation.

     [x] Write Visibility: Exports information about whether the object is visible or not. This can be useful for things like animation or simulations.

6. Export the Asset:

   - After configuring the settings, click on the "Export" button to save the .abc file.

Following these steps will allow you to manually export assets in a way that ensures compatibility with other programs. Keep in mind that this process may vary slightly depending on the specific versions of Maya and the other software you're working with.
