Directional light

Modified on Thu, 4 Jul at 2:53 PM

Launch the Lighting window from the sidebar and click  to create a new directional light.

Select a directional light to view and edit its parameters in the Object Inspector:

  • Color enables you to set the color of the light. 
  • Intensity sets the strength of the light. 
  • Shadow type lets you choose between soft, hard, and no shadows. Hard shadows have sharp edges and are fast to compute. Soft shadows are more realistic but may take longer to compute.
  • Strength determines the darkness of shadows ranging from 0 to 1, with 1 being the darkest. 
  • Near plane sets the distance from the light source beyond which objects cast a shadow. 
  • Bias can be increased to counteract visual artifacts. Avoid increasing it too much, as it can cause the shadow to appear disconnected from the object. 
  • Resolution of shadows is set to medium for point and spotlights and to very high for directional lights. Adjust as necessary to produce high-resolution shadows.

Finally, press (Re-)compute shadows from the Lighting tool. Remember that shadows need to be re-computed if you transform the light source.

When working with point clouds covering large areas, we do not recommend using directional light shadows.
