StudioMDL++ is a community-made modification of Source's StudioMDL developed by ficool2.

Differences

• Added AppID mounting in gameinfo.txt
• Added -nodx80 option to not emit .dx80.vtx files
• Added reverse command for $sequence
• Added pos and rot options to match command for animations
• Added copy command for animations
• Added basic if/else/else if conditionals to animations
• Added default argument support to macros
• Added new $endmacro terminator for macros, allows omitting \\
• Added numeric input support for $contents
• Added better warnings for invalid bounding boxes in animations
• Added -noremap to disable sequence remapping with existing models
• Added gmtime option for $sequences to flag as synced to UTC time
  • Note: this requires mod support
• Added check for overflowing cmdlists
• Added -cullanims parameter to remove unreferenced $animations
  • This can significantly reduce file size on large animation sets such as thirdperson animations
  • nocull parameter can be added to an $animation to disable culling
• Made offset optional for $attachment, can be explicitly defined with offset token
• Significantly faster compilation
• Raised maximum amount of bones in the SOURCE mesh to 1024 (the output bone limit is still 128)
• $collisionmodel and replacemodel no longer require explicitly providing extension name
• Implemented new rules for bone collapsing that prevent unexpected behavior, see below:
  • If bone is marked by $alwayscollapse, its always collapsed no exceptions
  • If bone is assigned to a vertex at any LOD, dont collapse
  • If bone is used as a hitbox, don't collapse
  • If bone is a $definebone, dont collapse
  • If bone is used in an animation, dont collapse
  • If bone is procedural, don't collapse
  • If bone is part of ikchain, don't collapse
  • If bone is used as $attachment, don't collapse
  • If bone is used as $bonemerge, don't collapse
  • Otherwise, collapse
• Fixed $renamebone not affecting the collision model
• Fixed crash if source bones limit is exceeded
• Fixed crash if blank bodygroup was used with $staticprop
• Fixed bogus animation data being printed in console
• Reduced default weight culling from 5% to 0.01%
• Removed limit for max number of animations
• Removed .sw.vtx output

Note:This is used for DirectX 6 and 7 feature levels, which have been unsupported since .
