V0.9.10

Please don't use this release, it seems to break some skinned meshes, use V0.9.9 instead for now

• Exporting combined meshes now produces a valid GLTF.

• Fixed a bug in the PBR shader assignment script that would always pick the orm texture pattern for normal maps. If you now want to combine occlusion, roughness and metallic, you should use _orm in your filename.

• If a PBR shader is found in the workspace, that one is used instead, so that everything can be stored in the workspace.

• The PBR shader will now apply sRGB conversion to the PMREM maps by default. Note that you often will want to disable this when using a DDS that is linear. However, Maya doesn't support HDR cubemaps. In the future we will support RGBM 8888 encoding so Maya can have HDR with standard DDS maps.

• Added a flag in the PBR shader to flip the Z direction of the PMREM lookup vector. This seems to result in correct mirrored reflections when using DirectX DDS cubemaps. Enabled by default.

V0.9.9 - first stable release

• The release script now generates a ZIP instead of RAR file, thanks @underthematjp for reporting this.

• I'm considering this plugin "stable" now.

• The 1.0 release will be made when the OSX cmake branch is merged, and when we exported all WonderMedia 3D characters to glTF

v0.9.8 ALPHA

NOTE: I consider this an alpha release, since a lot has changed internally, and the exporter might need more testing.

• The default extension is now gltf (lower-case). You can configure the extensions using the -gltfFileExtension (-gfe) and -glbFileExtension (-gbe) flags

• By default no more redundant shape nodes are exported. If you want to keep these shape nodes, pass the -keepShapeNodes (-ksn) flag

• Rotation pivots points are now properly supported. Scaling pivots points are ignored and assumed to be the same as the rotation pivot point.

  • An extra GLTF node with the :PIV suffix is created for the pivot translation (the vertices of the mesh are not changed anymore)
  • In theory even animated pivot points should be supported, but this is not tested yet.

• Passing -glb or -emb now correctly exports a single file.

• Support for double sided materials in the PBR OpenGL shader. See the PBR Advanced attribute group of the shader. Note that backface culling (in the Mesh Component Display accordion) must be turned off for correct rendering, but that setting has no impact on the exported file.

• Maya material names are now copied over to the GLTF materials

• Skeletons with multiple roots are now correctly exported

  • the GLTF skin.skeleton property is not set anymore, since its meaning is not clear

v0.9.7 BETA

• Fixed export of transparent materials (but you must explicitly set the Technique in the GLTF PBR Shader to Transparent for this to work for now)

• Uses lower case gltf extension

• Exporting a single frame does not "bake" the skin at that frame anymore when -initialValueTimes (-ivt) is specified, instead the skin binding pose is taken from the initial values time, and the GLTF nodes will be loaded with the transforms from the current frame (as if exporting a single frame animation clip; we use this to test our computer shader deformation engine without requiring animation)

• When the Maya mesh has texture coordinates, these will be exported by default, unless you pass excludeUnusedTexcoord.

v0.9.6 BETA

• PBR material base color factors should now export correctly (thanks to @Chase-Reid for reporting this regression bug!)

• When assigning the PBR material, the default path for the shader is used, so the user doesn't have to pick the shader file anymore.

v0.9.5 BETA

• Added PBR files to the release ZIP
• Added refresh button to the UI
• Added more keyword patterns to the PBR texture importer

v0.9.4 BETA

Fixes

• Fixed inverse binding matrices of skin bound to meshes with a pivot point

Installation

Maya 2018 and 2017, Windows x64 only for now.

To install, extract the ZIP to any location (e.g. your desktop), open the created Maya2glTF folder, and double click on the deploy.bat file.

Then re-launch Maya 2017 or 2018, and in the script window, type maya2glTF_UI to launch the UI. Load a scene, select the meshes you want export, and hit the export selected meshes button.

Let me know if this works for you, this is BETA stuff ;-)

PS: You might have to install the Microsoft Visual C++ redistributables to get it running correctly.

v0.9.3 BETA

Fixes

• Fixed exporting multiple animation clips
• Added support for exporting TRAX clips in the MEL UI
  • only enabled clips from the first track are exported

Known issues

• The animation clips of the skinned complex1 scene doesn't play correctly in BabylonJS and ThreeJS. Most likely because of a combination of a pivot point and skinning. To be investigated.

Installation

Maya 2018 x64 only (tested on Windows 10 ) for now.

To install, extract the ZIP to any location (e.g. your desktop), open the created Maya2glTF folder, and double click on the deploy.bat file.

Then re-launch Maya 2018, and in the script window, type maya2glTF_UI to launch the UI. Load a scene, select the meshes you want export, and hit the export selected meshes button.

Let me know if this works for you, this is BETA stuff ;-)
