If you're working with XGen in Maya and need to export your hair and fur to OBJ format, there are a few steps you'll need to follow to ensure a smooth transition. Here's a simple guide to help you through the process:

Step 1: Prepare your XGen collection

Before you can export your XGen hair or fur, you'll need to make sure that your collection is ready for export. This includes grooming and styling the hair/fur to your desired look.

Step 2: Convert your XGen to geometry

In the XGen window, select 'Description' and under the 'Utilities' tab, choose 'XGen Convert Primitives to Objects'. This will convert your XGen hair or fur to actual geometry that can be exported as an OBJ file.

Step 3: Export as OBJ

Once your XGen primitives have been converted to objects, go to 'File > Export Selection' and choose 'OBJ' as the file type. Make sure to select the appropriate options for your export, such as whether to export normals and UVs.

Step 4: Import the OBJ file into your desired application

Now that you have your OBJ file, you can import it into any 3D application that supports OBJ format, such as Blender, Unity, or 3ds Max. Your XGen hair or fur will now be available for use in your new environment!

Keep in mind that when exporting XGen to OBJ, you may encounter some limitations, such as losing the procedural nature of the hair/fur or the inability to edit the grooming after export. However, this method provides a way to transfer your XGen creations to other programs for further development or integration into larger projects.

In conclusion, exporting XGen to OBJ format is a relatively straightforward process that opens up a world of possibilities for leveraging your XGen creations in other 3D applications. By following these steps, you can ensure that your hard work in Maya is not confined to just one platform, but can be shared and utilized across different software environments.
