Ambient Light object

Adds a constant level of light to every surface in the scene (or in the light’s mask), coming from no specific direction.

Parameters

Ambient Color

Light color

Light Intensity

A scale on the color. If the intensity is 0, the light disabled. The light will only be sent to the renderer if the object is included in the “Force Lights” parameter of the output driver.

Light Enabled

Turning this toggle off is equivalent to setting the light intensity to 0.

Enable Light In Viewport

Turning this off removes the light from consideration in the viewport. This is useful for lights which only make sense at render time.

Display

Whether or not this object is displayed. Turn on the checkbox to have Houdini use this parameter, then set the value to 0 to hide the object, or 1 to show the object. If the checkbox is off, Houdini ignores the value.

Viewport Selecting Enabled

Object is capable of being picked in viewport.

Select Script

Script to run when the object is picked in the viewport. See select scripts .

Cache Object Transform

Caches object transforms once Houdini calculates them. This is especially useful for objects whose world space position is expensive to calculate (such as Sticky objects), and objects at the end of long parenting chains (such as Bones). This option is turned on by default for Sticky and Bone objects.

See OBJ cache preferences for how to control the size of the object transform cache.
