- A new Raytracer dialog appears, which allows you to set the "Environment" color node parameter. The Environment parameter is used to specify the color of rays that do not hit any object.
- Click OK in the Raytracer dialog.
- Bring up the slider underneath the Reflection or Refraction input so you can see the effect of the ray tracing.
- If you are using ray tracing to simulate refraction, set the "Index of Refraction" input for the material. Note that if the index of refraction is 1.0 light is not bent at all.
- Click OK in the ShaderMaker dialog.
- Render your scene.

3DMF Import
Pixels3D now has the ability to import 3DMF files. 3DMF is Apple's file format for QuickDraw 3D. The importer can read in Tri-Mesh, Tri-Grid, NURB, and three or four sided polygons. If the file contains polygons with more than four sides, you will be given a warning indicating that some of the polygons are not being imported.
