Receiving Messages

 
 
 

Location:

The mental ray rendering software can provide detailed messages as it reads and renders a scene. You can use these messages to help you fine–tune for quality and performance. For example, keeping track of triangle count, etc.

You can choose to output any combination of the following message types by checking the corresponding checkbox:

When rendering from the command line, use the -verbose argument.

NoteTo write the verbose messages to a file, you must set command–logging to file in the Scripting Preferences.

Displaying Messages

Verbose messages are logged to the script editor, and/or the log file. To see the verbose output, simply open the script editor by choosing View Scripting Script Editor from the main menu.

Reading Messages

The following table will help you understand logged messages:

Message Code

GAPS

GAP scheduler that routes approximation requests

GEOM

Geometry modeling operations

GEOT

Geometry conversion for tessalation, a submodule of GAP

IMG

A

These letters correspond to the mental ray module that is supplying the verbose message. Modules are listed in the table above.

B

Two numbers separated by a period represent the number of the machine on the network (if distributed rendering) and the number of processors used during rendering.

C

This word defines the message level. Levels are: fatal; error; warn; info; progress (progr); debug; or verbose debug (vdebug).

D

These seven numbers correspond to the code number of the warning, error or fatal error.

E

The remainder of the verbose message is in English and specifies a warning or error.
