Hotfix - Autodesk 3ds Max 2008 - 2009.03.24

This hotfix addresses the following issues:

3ds Max Core Application

• We addressed a program error where a Customer Error Report would appear when exiting the program. This would typically occur when running two simultaneous sessions of 3ds Max.

Biped

• Biped copy files (CPY) containing postures, poses, and tracks created in versions of 3ds Max prior to 3ds Max 2008 would become corrupted when saving copy files with postures or tracks and would not open in 3ds Max 2008. This has been fixed.
• Previously, in some situations, after selecting parts of a Biped and then selecting multiple keys on the track bar, a memory leak would occur. Eventually this could result in other application instabilities or a program error. This problem has been fixed.

MAXScript

• The Garbage Collector has been modified to better manage memory. In this way, we are significantly reducing the loss of the Undo stack during automatic garbage collections and increasing the amount of memory freed while performing a ‘gc light:true’ garbage collection.

mental ray

• Scenes that contain settings that require mental ray to log progress take much longer to render when using network rendering. Examples of this issue are found when rendering shadow maps, scenes containing placeholders, SSS shaders, and light maps with Backburner or command-line rendering. This performance issue has been resolved.

Rendering output and bitmap file chooser

• When defining output paths and filenames the first time, the capitalization would be saved properly, as input. On subsequent opening of this dialog, the filename and path would be converted to all lower-case. This fix keeps the proper case as set by the user.

SDK

• When using the IGameExporter a vertex could have an invalid normal value. This problem could occur if you have a nearly degenerated triangle in its own smoothing group or if two triangles share an edge and the same smoothing group with exactly opposite normals (such as a two-sided triangle). The exporter has been fixed to address these situations.

XRef

• In some instances, when a file contains XRef Scene data and all objects are selected, using the Arc Rotate viewport control could result in a program error. This has been fixed.
