- In the drawing, click the light glyph.
- In the Attenuation panel under the Lighting Properties Tab of Properties Inspector:
- Select a type of attenuation.
- Inverse Linear (Standard lights only). sets attenuation to be the inverse of the linear distance from the light.
For example, at a distance of 2 units, light is half as strong as at the point light; at a distance of 4 units, light is one quarter as strong. The default value for inverse linear is half the maximum intensity.
- Inverse Square (Photometric lights). sets attenuation to be the inverse of the square of the distance from the light. For example, at a distance of 2 units, light is one quarter as strong as at the spotlight; at a distance of 4 units, light is one sixteenth as strong.
- None (Standard lights only). sets no attenuation. Objects far from the point light are as bright as objects close to the light.
- Inverse Linear (Standard lights only). sets attenuation to be the inverse of the linear distance from the light.
- Select a type of attenuation.
- Check the Use Limits checkbox. The default is no. (Standard Lights only)
- Enter Start Limit Offset to specifies the point where light starts as an offset from the center of the light. The default is 0.
- Enter End Limit Offset to specifies the point where light ends as an offset from the center of the light. No light is cast beyond this point.
