This recipe will show you how Lit Sphere materials can mimic materials from other 3D programs. Using this material you will be able to use materials from other software by rendering out a sphere and applying it to a Lit Sphere material in Mudbox. This material uses the shading information, within the rendered sphere, to determine the shading of the Lit Sphere material.
The following steps will help you get ready to be able to use Lit Sphere materials:
1. First you will need to render a sphere with the material of your choice from another 3D program as shown in the following screenshot:
2. Next, you should extend the color on the edges of the sphere out to the edges of the texture and save it. I've added some color to the light sources of this texture so that you can easily see what is going on.
3. Now that the texture is created, we can start building our material.
