Differences

Significantly faster compilation
Significantly improved loading speed of SMD files
Supports compiling unlimited number of vertices and materials
Raised maximum output file size to 32mb
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 $bbox meshname 1 meshname 2 ... to calculate bounding box from specified mesh only
Added $setvariable - similar to $definevariable but can override a previous variable
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
Added warning if duplicate variable is defined via $definevariable
Added error if duplicate macro is defined
Weight for "activity" is now optional, defaults to -1 if not specified
Made offset optional for $attachment, can be explicitly defined with offset token
Missing bone name in $weightlist is now a warning instead of error
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
Unused materials are now removed from the final model (i.e. part of $animations or collision model only)
Macros now fallback to $definevariables if not found in macro parameters
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 crash if source mesh had too many vertexes/faces
Fixed swapped variable names in missing control bone X for procedural bone Y error
Fixed bogus animation data being printed in console
Reduced default weight culling from 5% to 0.01%
Removed limit for max number of meshes and animations
Removed .sw.vtx output
