Shadow Map Tutorial

Creating a shadow map using the RenderManShadowMap plugin:

Create or select an existing RenderManLightShader node.
Choose a light shader that uses shadow maps, such as k3d_distant_shadow.sl.
In the shadow map property for the shader, choose --New RenderManShadowMap.
The new shadow map node is basically a special-purpose render engine.
Choose a camera to be used by the shadow map. The camera will control what the shadow map "sees".
Typically, you will want to parent the shadow map camera to the light source that will cast the shadow.
Assign the shadow map camera to a viewport panel, so you can see what the shadow map will "see".
Use the transformation tools to position / orient your light source.
Render.
