Shell Material for Texture Baking

The Shell material is for use with texture baking.

• Render to a texture. > Material Editor > Pick Material from Object > Click object with baked material.

When you use Render To Texture to bake a texture, it creates a Shell material that contains two materials: the original material used in the rendering, and the baked material. The baked material uses a bitmap that is saved to disk by Render To Texture. It is “baked,” or attached to an object in the scene.

The Shell material is a container for other materials, like Multi/Sub-Object. It also lets you control which material is used in which renderings.

Note: The Material/Map Browser lists the Shell material when you assign a new material. You can apply two materials to a single object this way, but changing a material's type to Shell does not generate a baked texture that is saved to disk.

Procedures

To load a shell material into the Material Editor:

1. Click an unused sample slot. (In the Slate Material Editor, the sample slots are in the last group displayed by the Material/Map Browser panel.)
2. Click (Pick Material From Object).
3. In a viewport, click an object that has a baked material.

   The sample slot now contains the baked material.

   • In the Compact Material Editor, the Shell Material Parameters rollout is immediately visible.
   • In the Slate Material Editor, drag the sample slot into the active View as an instance, then double-click the Shell mode so you can see the material’s parameters.
