Open the scene for the lesson
In this lesson, you work with a scene we created for your use. In the first steps
of this lesson, you open the scene and view the various elements that have
been preset for your use.
1 Make sure youve done the steps in
Preparing for the lessons on page 377.
2 Open the scene file named CausticStart.ma.
This file can be found in the GettingStarted directory that you set as
your Maya project:
GettingStarted\Rendering\CausticStart.ma
The scene contains a still life with a translucent bottle and apples. Other
surfaces act as the floor and walls for the scene. (The bottle appears opaque
when viewed in shaded and textured display mode.)
Two lights illuminate the scene: a spotlight and a point light.
Shading materials have already been assigned to the models and surfaces.
You can view the shaders and textures by opening the Hypershade editor.
When you initially render this scene, the objects cast shadows onto the
floor surface. Caustics are added to the lighting of the scene to create a
more realistic shadow for the translucent bottle.
