  • Change the type of layer: Click the sphere icon, and then click a type of layer (choose from Basic, Metal, Glass, Thin Glass, or SSS)
  • Define the weight of the layer: To change the %, drag the colored horizontal bar. Or to select a bitmap, click the checkerboard icon
  • Delete a layer: Click the layer, and then click the trash can icon
  • Move a layer: Click the layer, and then click the up or down arrow

Material Preview

The material preview can be maximized by double-clicking on it. More options can be found when right-clicking on the preview:

  • Load Material: Loads a .mat.thea / .mat.pack Thea Material
  • Save Material: Saves the current material to .mat.thea / .mat.pack files
  • Save Preview: Save the material preview as an image
  • Room Selection: Select between different kind of room previews (e.g. cloth, direct, floor, etc)

Material formats explanation

.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.
