If you've been working on 3D modeling in Maya using XGen and need to export your work to OBJ format, you've come to the right place. Follow these simple steps to successfully export your XGen creation to OBJ:

Step 1: Select your XGen Collection

In the Maya interface, navigate to the Outliner and select your XGen collection that you want to export. This is the set of your groomable splines, feathers, or instance-based geometry that you want to convert to OBJ.

Step 2: Convert XGen to Guides

Go to the XGen Interactive Grooming shelf and click on 'Convert to Guides.' This will convert your XGen splines to Maya's nHair curves, which can then be easily exported to OBJ format.

Step 3: Create Output Modifier

In the Attribute Editor, find the Output Modifier section and click on the 'Add Output Modifier' button. Then choose 'Description' to add a Description modifier.

Step 4: Export as OBJ

With your XGen collection still selected, go to 'File' > 'Export Selection.' In the Export window, choose OBJ as the file type and select the directory where you want to save your OBJ file. Make sure to check the options for exporting Selection and the Materials and Textures if you want to include them.

Step 5: Set OBJ Export Options

In the OBJ Export Options window, you can adjust the settings according to your preferences. You can choose to export the Normals, UVs, and Materials. Once you're satisfied with your settings, click 'Export' to save your XGen collection as an OBJ file.

And that's it! You have successfully exported your XGen collection to OBJ format. Now you can use your creation in other 3D modeling software or share it with others who may not have access to XGen.

Exporting XGen to OBJ is a straightforward process in Maya, and with these simple steps, you can ensure that your work is saved and ready for further use. Whether you're a beginner or an experienced 3D artist, mastering the export process will open up new possibilities for sharing and collaborating with your XGen creations.
