Lights · Rhino

In Rhino, D5 Lite reads native Rhino lights and does not provide a separate Lite light panel. You continue to create and edit lights in Rhino; Lite reads them and shows the corresponding render result.

Light Types

Rhino light	Lite render result
Point Light	Point Light
Spotlight	Spot Light
Linear light	Strip Light
Rectangular light	Rectangle Light

Rhino's directional (parallel) light is not read as a Lite light. Rhino also has no native light type equivalent to a Disc Light, so there is no Disc Light in Rhino.

Reading and Editing

Lite reads the position, orientation, color, intensity, angle, and size of Rhino lights; the Spot Light direction follows the light direction in Rhino. After you adjust a light in Rhino, the Lite render updates with the sync.

Shadow Thickness and Light Radius

Rhino has no separate Lite light panel, so Lite expresses light radius through Rhino's native Shadow Thickness parameter: a shadow thickness of 100% corresponds to a light radius of 0 (hardest shadow edge) and 0% corresponds to 10 (softest), that is, Lite light radius = (100 − Rhino shadow thickness %) / 10. This mapping applies to point lights and spotlights only; rectangle lights and strip lights have no light radius.

Sync to D5 Render

Rhino lights can move into D5 Render via Live Sync for further refinement.
