3D Shadow Tab
Parameter Description
Shadow 1, 2, and 3
options
Control the shadows created by the three
corresponding light sources.
• Select the option next to the tab to turn on the
shadows created by the light source.
• Leave the option deselected to turn off shadows
created by the light source.
Shadow Bias Corrects render errors that may occur in creating the
shadow as follows:
• Default maintains the Shadow Bias in its current
state.
• Increase Shadow Bias to adjust noise on
unshadowed areas.
Decrease Shadow Bias if the shadow partially or
completely disappears.
Softness Softens the edges of the shadow.
• Higher values produce soft shadows similar to
those created by a diffuse or distant light source.
• Lower values produce harder shadows similar to
those created by an intense light source.
For best results, keep the Softness value greater than
zero. Softness values of zero can produce jagged
edges. If you notice jagged edges, increase Map
Resolution.
Map Resolution Adjusts the general accuracy of the shadow.
• Higher values produce more accurate shadows,
but increase render and preview times
significantly.
• Lower values reduce the quality.
