Lights Tab (for 3D Plane Shape)
Falloff Controls the rate at which the Specular light falls off
from the center of the lit region.
• A higher Falloff value creates a more
concentrated highlight, simulating a shiny,
highly reflective surface.
• A lower Falloff value spreads light more evenly
throughout the lit region, simulating a rougher,
less reflective surface.
Both Specular and Diffuse light are affected by
Color but only Specular light is affected by Falloff.
Parameter Description
Light tabs Click to select one of three light shapes. Select the

in space.
Cartesian: Lets you position the light source by
specifying X and Y coordinates and the distance
between the light source and the image.
Spherical: Moves the light around the shape along
an arc.
