Sweep Parameters (Lights Tab)
Cone Width Adjusts the size of the light cone.
• Increase this value to enlarge the size of the cone
base thereby making the lit area larger.
• Decrease to make the light cone narrower and
reduce the size of the lit region.
Unlike a physical spotlight, changing the cone width
of the light does not affect its intensity.
Intensity Controls the brightness of the spotlight. Unlike the
Diffuse Specular Intensity parameter, changing
Spotlight Intensity does not affect the size of the lit
area. Adjust using the Cone Width parameter.
Edge Falloff Controls the relative softness of the edges of the lit
region.
• Leave Edge Falloff at its default setting of 0 if
you prefer a hard edge on the spotlight effect or
increase this value to soften 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, you need to increase Cone
Width accordingly.
