Shadow in Maya


Shadows work with lights to add realism to your scenes. Shadows help to define the location of objects, whether they rest on the ground or hover in space, for example. Shadows can be soft-edged or hard-edged, and their presence (or absence) can be used to add balance and contrast to objects in your scene.

To create a shadow, a scene must contain a shadow-casting light, a shadow-casting surface, and a shadow-catching surface. The light must illuminate both the shadow-casting surface and the shadow-catching surface.

Default shadowing (none)

By default, lights in Maya do not cast shadows. You need to specify which, if any, lights cast shadows in your scene, depending on your visual goals. Too many shadows can clutter your scene, and since they take time to render, you may want to use as few shadows as necessary.

If no lights in your scene cast shadows, all surfaces facing a light source are illuminated, even if obstructed by another surface. (When light shines on a surface in Maya, the parts of the surface facing toward the light source appear illuminated, and the parts of the surface facing away from the light source appear dark.)

You can, however, add shadows by controlling which combinations of lights and surfaces can produce shadows. Typically, you only want a few specific lights and surfaces to produce shadows. By limiting shadows only to these specific lights and surfaces, you can help reduce rendering times.


In Maya, surfaces that are not illuminated are not considered to be shadows. For example, all surfaces facing away from a light source are not illuminated.
