The Import Settings window consists of three tabs:

- [Model](#model): to customize the Alembic file import through Scene, Time, Geometry and Camera options.
- [Materials](#materials): to map the submeshes of the imported Alembic asset with existing materials of your project.

There are two others screenshots in this page showing the Model/Material/Hair tabs. They should be also be updated I believe.

yes this is true! However, I discussed this with @sebastienduverne and the screenshots system will be getting overhauled soon so it's not vital to replace these screenshots yet. The sample information in the current screenshots have is meaningful and therefore it's better to keep these rather than having new images with all 3 tabs

Yeah I remember I said that – however for now there is no immediate plan to retake all screenshots across the doc (for context, it would be to switch to dark mode).
So if one of you could update the 3 consistently (reproduce what was shown as best as possible) and uniformly (get the same width and resolution for all), that would be cleaner. I can't really do it at the moment, I'm not set up for it.
Thanks!


### Generate Hair Asset

This button generates a Hair Asset based on the imported Alembic asset. For this, your Alembic asset must include curves data.

Once generated, the Hair Asset is independent from the imported Alembic file.

## Apply and Revert buttons

If you change properties in any tab of the **Import Settings (Alembic Importer)** window, the Alembic Importer does not take them into account until you manually apply them.
