3. Source power.

• Values from 1 to 1,000,000. Move the slider to change the power or enter a value.

4. Attenuation Distance

• Calculates the attenuation distance for the lighting power.
• Between the attenuation distance and source, the lighting power remains constant and at maximum.
• The distance beyond distance A corresponds to the gradual diminishing of lighting power at 1/d². When the attenuation value equals 0, the light diminishes at 1/ d² beginning at the light source.
• Enter the distance in the numerical field (current unit).

NB: in this area, the illumination principle is based on reality. The closer an object is placed to the light source, the more illuminated it appears.

5. Shadow slider has a value range from hard to soft.

• Activate/Deactivate Shadows: Click on the box to check it.

6. Change the Lighting Angle:

• By sliding from 10 to 360° or by typing in a numerical value.

• Example: A value of 360° provides an omnidirectional light. 120° produces a spot light.

7. Shadow lateral blur:

• sharpness slider on the edge of the illuminated area. Values from 0 (diffuse area between the shadow area and the illuminated area) to 1 (straight limit). Accepts a numerical value.

8. Lens Flare:

• Activate/Deactivate: Click on the box to check it.
• Choose effect: Click on one of the thumbnails:
• Halo Power: Move the slider or type in a value between 10 and 200%.

9. X, Y, Z coordinates: For the position of the light source and its target.

• Clicking onlocks them and clicking on unlocks them.
• Target on: Choose between target on a fixed vertex or on an object defines as target.
