Materials can be created in the same way you create Rhino materials.

To be able to see the new Thea Material option, Thea Render needs to be the active render engine. From the top menu select: Render > Current Renderer > Thea Render


There are two ways to add a new Thea material in the material list:

  1. Click on the + icon in the material panel and select "Thea Material" from the list
  2. Click on the Thea Content Browser icon
    a. Select a material
    b. Either click on the Add button or double‐click on it to add it in the material list

There are two ways to edit Thea materials. You can either use material presets as a starting point or use the advanced material editor to have complete control over the material parameters.

To start editing a material, select it from Rhino's material panel and click on the "Edit" button. This will bring up the Thea material editor window with the option to use it either in preset or editor mode.
