Lights

Lights illuminate the objects in your scene and help you accurately evaluate the form of your sculpted model. You can modify the brightness (intensity) and color properties (diffuse color) for a light and define whether it casts shadows. A default light exists in the 3D View but you can create additional lights.

The three light types are:

• Point - A point light source emits light evenly in all directions from an infinitely small point in space. A point light is often used to simulate an incandescent light source.
• Directional - A directional light source simulates a very distant point light source. Its light rays are parallel to each other, as if emitted perpendicular to an infinitely large plane. A directional light is often used to simulate a light source like the sun.
• Image Based - An image-based light source simulates lighting based on an environment image you specify and generally provides a more even illumination compared to other light types. You can have only one image based light in the 3D View at a time. High Dynamic Range Images (HDRI) are supported and a few sample HDR images are provided in the following directories:
  • (Windows) <drive>:\My Documents\Mudbox\<version>\data\Textures\Lightprobes
  • (Mac OS X) /Users/<username>/Library/Application Support/Autodesk/Mudbox <version>/textures/Lightprobes
  • (Linux) /home/<username>/Mudbox/<version>/Textures/Lightprobes
