= Viewport Shadows =

Once you have lights in your scene, you can set up your display options to display shadows in the viewport. This makes it easier to determine what shadows will look like at render time.

== To display shadows in the viewport ==

* Set up lights in your scene.
* Turn on shadows on the __Shadow__ tab of the light node.
* On the __Misc__ tab of the [3D viewer Display Options window|/ref/windows/displayopts_3d], turn on the __Shadows__ checkbox.
    You can also turn on the __Projected Textures__ checkbox which will clean up the look of your shadows.

NOTE:
    Displaying shadows in the viewport may slow down Houdini, since it needs to generate a shadow map for each light casting shadows.
