[chimerax-users] Exporting scene with .obj and .mtl file

Hello, I need to export an obj file along with the associated mtl file, however, under the “file > save” option, there is only an option for saving as .obj, not .mtl. I read in the online documentation that there should be the capability to “export a scene” which saves an obj and mtl file, however I do not see this option when using v 1.6.1. Is this still supported? Thanks, Zack
