Hey Mattehw Liu , what are you missing when it comes to metal materials in Rhino?
Please be aware, that we now also offer a dedicated material editor for Rhino (in our latest preview, check out how to acquire that version here) which allows you fine-tune your materials more easily in general now, like you can do in SketchUp!
Before being able to configure your materials via our material editor, you'll first have to set the material type (of the materials you want to edit) to "Enscape":
Kindly let me know if this doesn't suffice or in case you have any further feedback or questions.
- Thank you very much for your reply! It helps me a lot.
