Environment

The Material > Environment sub-palette has controls for material shadows and ambient occlusion in BPR renders.

Shadow

Apply BPR shadows. Use this slider to control the intensity of the shadows being cast on a Tool and/or SubTool(s) using the selected assigned material. The Render > BPR Shadow settings then control the quality of shadows being cast onto the Tool and/or SubTool(s).

Ao

Apply BPR Ambient Occlusion. Controls the intensity of ambient occlusion being applied to a Tool and/or SubTool(s) using the selected assigned material. Ambient occlusion darkens surfaces that are close to other surfaces (such as where a wall intersects with the floor), simulating how shade naturally pools in areas where surfaces are close together. The Render > BPR Ao settings then control the quality of the ambient occlusion being applied to the Tool and/or SubTool(s).

Vibrant Shadows and Ao

When the Vibrant Shadows and Ao button is pressed shadows will have a more saturated color. This option can be turned on or off individually for each shader channel.
