Rhino 7 has introduced new light falloff types, including Linear and Inverse Squared. What light falloff does is decrease the light’s intensity as it travels through the scene, which closely parallels what happens in the real world.
New Updates
There are several new updates involving lighting in Rhino 7, in addition to the new falloff types.
Under Sun lighting settings, the user can now double-click the Skylight to open the Rendering panel. Under Lighting Properties, under Intensity, the user can now drag the slider beyond the right end of the slider range to increase intensity above 100 percent.
New Light Falloff features add better rendering realism in Rhino 7.
New shadow intensity controls the softness of the shadow cast by the light. This is only visible to see the change in reflection in the raytraced mode of rendering.
Falloff, with the exception of directional lights, has new Linear and Inverse Squared modes. Under Constant mode distance has no effect on light intensity. Linear decreases light intensity at a constant rate (not to be confused with the Constant mode setting). Another word to describe it would be light intensity drops off at a fixed rate.
How the Inverse Squared falloff light settings look mathematically via chart.
Inverse Squared drops light intensity at an ever decreasing rate (as opposed to a fixed rate), so distance sees light fall off rapidly. (see image above).
