Light Linking#

Clarisse offers quite a few ways to manage lighting and link links to the elements of the scene. Light linking can be achieved:

• on Render Scene/Layer 3d by directly specifying a group of lights to Lights attribute. Please refer to here for more information.
• on Scene Objects by specifying a group of lights to Lights attribute.
• on Lights by specifying a group of scene objects to the Shadow Group attribute to control which ones are occluders for the light.

Let's imagine, we have 3 geometries (a cube, a sphere and a polygrid) and 2 spot lights (on blue and one red). By setting the red light to the Lights attribute of the sphere and the blue light to the Lights attribute of the box, sphere receives only the illumination from the red light while the box receives the one from the blue one.

Default Scene

blue light isolated from the sphere and red from the box

It is also possible to specify the shadow group of each lights so that the red light only is only occluded by the sphere and the blue one by the box.

Default Scene

box is occluder of blue light, sphere of the red one
