Edge Falloff Controls the relative softness of the edges of the lit
region.
• Leave Edge Falloff at its default setting of 50 if
you prefer a soft edge on the spotlight effect.
• Increase this value to harden the edges of the lit
region.
Edge Falloff removes light from the edges of the lit
region.
To maintain the size of the region while softening its
edges, increase Angle accordingly.
Light X
Light Y
Position the light source in space by moving the
light parallel to the image plane along the X and Y
axes.
The light sources in 3D Extrusion are modeled as
non-directional point sources. As they move closer
to a specific region or face of a 3D object, the light
illuminates the region fairly evenly.
Distance Positions the light source relative to the image
plane.
• Negative Distance values place the light behind
the object and move the light away from the
viewer.
• Positive Distance values bring the light source
closer to the viewer.
