nekomdl (modified studiomdl)

this content is useless if you are not a modder.

Supports glTF, FBX, VRM and other formats. Please set the DMX export version to Binary5 Model 18.
Due to a compiler algorithm bug, too many vertices of a material in a single file (the exact number is uncertain) will cause a stack overflow, so the file will be automatically split when the number of vertices in a single file exceeds $MaxVerts.
When the compilation of a complex model fails (the generation of the vtx file is interrupted), try to reduce $MaxVerts and increase $FileBufferSize (8/16/32/64/…).
Supports up to 128 materials.
For other features, please refer to the attached changelog and NewCommands.qci

• New qc command: $RenameMorph

• New qc command: $MaxBones

• Increase the maximum number of flexed vertices to 511451.
• New qc command: $FileBufferSize; default is 8mb. if your model has very much detail, or very much animation, a larger file buffer will be needed. Increase its size appropriately to prevent compilation failures, and the compiler will also take more memory.

• glTF&Assimp: fix wrong end frame causing compilation failure
• Fix the bug that $CmdList can’t be parsed

• Increase the maximum number of vertices in a single source file to 51w (511451), beyond which it will be split automatically.
  make sure $NoDecal is turned on in vmt, or make sure the number of vertices in each source file does not exceed 65536.
• Fix a bug that prevented compilation.

• New $Animation option: AppendScale
• Fix a bug in glTF reading

• New command: $NoFastGltf
• Fix some bugs

• Fixed inability to correctly parse filenames without extensions.
• Using caching to improve loading speed of ‘innode’ options.
• glTF and Assimp: fix the animation used by default when ‘pick’ is not used.

• Fix ‘InNode’ error.

• glTF support for animation, default up axis changed to Y, support for node transforms。
• Throw away the FBX sdk.
• Use Assimp model loading library, supports over 40 formats including FBX, PMX, VRM. Support for Animation/SceneNode/Mesh/MorphTarget.

• New qc command: $FPS, sets the default animation frame rate and the animation sampling rate for glTF or Assimp.
• New source file parameters: ‘InNode’, ‘SampleRate’, ‘Pick’. Ability to load part of the meshs or one of multiple animations in a single file. Only support glTF&Assimp(FBX..).
  More details in the NewCommands.qci file.
• $UpAxis added parameters: ‘glTF’, ‘Assimp’
• DMX: Does not display an error when a vertex has too many influenced bones.

• New commands: $JiggleBoneRealign, $ReverseJiggleBoneRotation.
• Use meshoptimizer instead of forsyth to optimize vertex caching, nvtristrip is no longer recommended.

• Upgrading to 64-bit.
• The program is completely independent and no longer depends on the external vphysics.dll.
• Floating point numbers support scientific notation.
• Fixed the problem that after using $PushD, the source file with the absolute path could not be read normally.
• $IF macro support || operator.

• Fix $NekoDriverBone not supporting bones with “.” bone names
• Fix not recognizing source files with uppercase suffixes in qc.

• Adjust the maximum number of materials to 128。
• Use UTF8 encoding.

• Fix a bug in $DefineVariable.
• Fix a bug in $EndIF.

• The $if command supports ‘==’ and ‘!=’ expressions.
• Fixed unused bones not collapsing.

• When the obj model cannot find the material texture, use the material name instead of "debugempty".
• obj model $Scale support.
• Enter standalone mode when the command line parameter does not include "-game".
• Added qc commands: $if,$ifdef,$elif,$eldef,$else,$endif,$UndefineVariable,$Msg.
• Supports defining variables through command line parameters, usage: [-D<variable_name> <value>]

• Added fbx animation support.

• Added "debris" as a valid option for $Contents.

• Fixed: Will not collapse bones with vertex weights.
• Changed: Bones that have only been used by $Attachment will not collapse.

• Changed: Do not collapse bones with no vertex weights used by $Attachments and $Bonemerge.

• Added: $NekoModel flex related parameters for FBX and DMX support. The usage can be found in the example qc.
• Added: Fallback to use FBXSDK to parse fbx files, upgrade sdk version to 2020.3.2.
• Added: Use the libraries required for static linking, no more dlls. note that when compiling models with $CollisionJoints, need to load vphysics.dll in the game directory.
• Added: Does not compare sequence differences with the mdl file to be overwritten. This can be turned on with the command line parameter [-checksequenceorder].
• Added: Hot reloading hlmv without checking if the title bar is the same as $ModelName.

• Fixed: When the driver bone of $NekoDriverBone is the parent of a procedural bone, the angle calculation of the procedural bone is incorrect.
• Added: New command line parameter: "[-reloadhlmv]", which will hot-reload HLMV after successful compilation.

• Added: New command line parameter "[-blender <path>]", tells the compiler the directory where the Blender executable is located.
• Changed: Call Blender to convert FBX to glTF. FBX now has the same functions as glTF. No longer dependent on fbxsdk.

• Added command line parameter [-maxbones <number>] to set the maximum number of bones in the compiled model

• Changed: Modify the file buffer size in other places, now the entire model can have up to 1 million triangles.
• Fixed: When automatically splitting a model with too high number of vertices, the split part will become an empty model.
• Added: support for glTF unskinned meshes.
• Fixed: glTF does not support $lod command.

• Changed: Increase the buffer size for writing files to prevent high-polygon models from causing memory overflow and crashes.
• Changed: New icon

• Added: $NekoModel supports eyeball and eyelid options
• Changed: The maximum number of cmds for animation is 128
• Added: gltf mesh $scale support
• Added: Apply $scale and animation parameter scale when reading animation parameter "forceboneposrot"
• Added: $scale support for dmxeyelid, eyelid, eyeball

• Fixed: Parameter "-outdir" does not support relative paths

• Added: command line parameters "-modelname"&"-outdir"
• Added: glb morph targer(shape key) support

• Added: support gltf morph targer, glb not supported yet
• Added: new qc command "$NekoModel", support gltf using flex
• Changed: $hbox does not write information about the capsule
• Fixed: "noautodmxrules" causes error report
• Changed: $NekoDriverBone logic, supported bone collapse
