Use the full material editor to create a complex material with multiple layers.
You can create multiple layers of different types and weights.
The material preview can be maximized by double-clicking on it. More options can be found when right-clicking on the preview:
.mat.thea: This material file format contains the definition of the Thea Material but not the textures used.
.mat.pack: Same as the .mat.thea format but packs all the textures in it.
Use drag and drop between channels with the left mouse button to copy a bitmap, color or procedural.
Below the Layers section, you can find the parameters of the currently selected layer.
Display advanced parameters: To display advanced parameters (Translucency, Micro Roughness, etc.), click the hamburger menu icon.
Holding down the Control key in the keyboard allows you to select multiple options.
Displaying all the Material Layer Properties at once:
It is possible to display all the material layer properties at once. Go to Extensions > Thea Render > Preferences and switch to the Advanced Tab. Check the "Show all material layer properties" option.
