MTOR 1.3 Release Notes

Summary of Changes to MTOR 1.3

Changes in 1.3 B04

• Fixed bug where vertex variables were incorrectly emitted for subdivision surface objects.
• Added scripting command for obtaining full pathname to master appearance. See Scripting commands for more information. See command: mtor appearance master -abs.

Changes in 1.3 B03

• Support for primary visiblity attribute
• Don't render particles participating in soft body dynamics
• Fixed bug where spotlights with attached cameras would not render correctly.

Changes in 1.3 B02

• Fixed bug in standalone MTOR mode where project searchpaths were not correctly set. This was due to new Maya 2.0 behavior not correctly setting current project directory until after a file had been completely read in.

Changes in 1.3 B01a

A couple of minor bugs were introduced with the B01 release that were important enough to fix quickly.

• Fixed bug where polygons rendered black.
• Fixed bug where searchpath entries were not correctly seperated by a colon.

Changes in 1.3 B01

• Updated internal RAT programming version number to 330.
• No longer do we store referenced appearances in the referencing scene file.
• Fixed bug where using "Once-per-job" shadows or reference geometry caused a runup from frame zero to current frame.
• Fixed shdmap bug on O2 machines.
• Fixed bug parsing .sli files. Now you can have defaults for strings and texture parameters.
• Added support for default parameter expressions in .sli file.
• Added new TCL expression: txmake. This simply converts a pathname to a source image into a canonical form. No texture conversion is performed by this proc.
• MTOR now output RiCoordinateSystem for all MtorCoordSysShapes. Note that only the shape node and not its parent transform makes it to the RIB file. You can now refer to a coordinate system shape by name as a string shader parameter.
• Changed default naming for MtorCoordSysShapes. Now they're more likely to be unique. To be completely sure and avoid coordinate system name conflicts, you should still rename the shape nodes to a scene-wide unique name.
• Fixed problems associated with light links.
• Added support for the RenderGlobals: shadowObeyLightLinks attribute.
• Added new scripting variable SEARCHPATHS which contains a space-separated list of directories in the project searchpaths.
• No longer do we save referenced appearances in the MTOR partition. Maya scene filesizes are reduced significantly if the scene refers to apeparances from other files.
• Glimpse now displays the namespace associated with referenced appearances.
• Added support for colored mesh vertices. Now you can use artisan to paint vertex colors for meshes and subdivs.
• Added new mel scripting commands to control project location and searchpaths. Available via the mtor project subcommands.
• Fixed particles with Maya 2.0. Internal Maya attribute had been renamed from renderType to particleRenderType.
• Glimpse temporary palette files can now be redirected. Prior releases automatically opened these temporary files in the /tmp directory. Glimpse now support more standard Unix convention. In priority, highest to lowest, Glimpse will use the following:
  • directory as defined by GLIMPSE_TMPDIR environment variable.
  • directory as defined by TMPDIR environment variable.
  • system wide temporary directory as defined by P_tmpdir variable in stdio.h header file.
• Fixed bug where penumbraAngle was not correctly output to RIB file, when penumbraAngle was exactly equal to 0.0.
• Fixed bug where Glimpse would not load shaders relative to the MTOR/Maya project directory.
• Fixed bug where relative texture references were incorrectly returned with first character being truncated.
• Modified magicSurf shader bump scaling to allow user to select the scaling space. Shader now supports "world" or "object" in addition to the default "shader" space for bump scaling.
• A change has been made in which the MTOR standalone executable is linked. This change causes MTOR to ignore the /usr/aw/maya symbolic link, and to always try MAYA_LOCATION when loading the Maya libraries during initialization
• Updated MTOR subdivision surface visualization plugin to work with Maya 2.0.
