PRB: OZ Glow Output Shader Does not Work in Render
Last reviewed: September 16, 1996

Article ID: Q156017

The information in this article applies to:


 * Softimage 3D for IRIX, version 3.5

SYMPTOMS
The OZ Glow output shader works in the Preview but not in the Render.

CAUSE
The most likely cause for this is that Adaptive Supersampling, an option in the mental ray Antialiasing dialog box, is toggled off.

RESOLUTION
You can use the following steps to correct this problem by activating the Antialiasing option:


 * 1) Go to the Matter module, and choose Render.
 * 2) In the Render Setup dialog box, click Antialiasing. The SOFTIMAGE Antialiasing dialog box appears.
 * 3) From the dialog box, activate Adaptive Supersampling.
 * 4) Also confirm that Active is toggled on. The Glow output shader only works in render if both Adaptive Supersampling and Active are activated.
