LightWave lights don't have to act exactly like lights in the real world. For instance, you can choose not to see a LightWave light source, only its illuminating effect in the scene. This is actually a handy feature because unlike a movie set, you can place lights anywhere, including in front of the camera.

Basic Light Attributes

Light Properties are to be found by selecting a light and hitting P or using the Properties button just to the right of the Current Item dropdown. This will bring up the Light Properties panel. This panel can vary quite a lot in size depending on what sort of light you’ve chosen, but they all have options at the top of the window in common.

Warning

Turning Cast Shadows on in the Shadows tab makes the light behave like an object casting a shadow created by other lights in the scene. Turning Cast Shadows on for a light is basically turning the light into a light blocker

Affect Volumetrics

Lights can optionally affect volumetrics for creating volumetric lighting effects or affecting volumetric primitives from the outside.

Warning

Volumetrics require an Inv Distance ^2 falloff. In 2018, this is set by default, but if your light is not affecting volumetrics check this setting first.
