You probably need to convert your XGen primitives to Maya geometry before exporting your objects to another 3D application. s. Another workaround is to delete the reference, create new reference, deleting the parent's xgen file and saving (so that new xgen file is created). Bind the geometry to the Description. I used the "Curve to Tube mesh" tool to convert hair to polygon. Ahhhhhhh Hi everyone, To start I'm currently using Maya 2016 and I'm having an issue with getting XGen to reference into another Maya scene.
