Use the Object Merge surface node to grab geometry from other objects' geometry networks. As soon as I do that, I get a prompt "SpeedTree ERROR: Material creation failed. Assuming you have a group, or a name attribute in order to separate leaves and bark, you can use the SOP "material" node, which is used to assign materials, and assign your two materials from there, setting the path of your materials in the "material" parameter field, and the primitives affected by it in the "group" parameter field. 5s to get started importing animated Rigged characters.
