v0.9

Converter

• Add texture and material attribs to fallback RenderState
• Add option to convert PBR glTF materials to "legacy" materials
  • This is best effort and data will be lost
  • Exposed in GltfSettings as legacy_materials (defaults to False)
  • Exposed in gltf2bam as --legacy-materials flag

v0.8

Converter

• Add support for joint/bone parents
• Add support for PANDA3D_physics_collision_shapes extension (includes new intangible setting)
• Fix errors when using double-precision builds of Panda3D
• Fix ZeroDivisionError when loading single-frame animations
• Fix loading meshes with no indices
• Fix loading model tangents on Z-up files
• Fix generating tangents on Z-up files
• Fix the sign on generated bi-tangents

v0.7

Converter

• Fix error when no top-level extensions object is present
• Fix crash when using Panda3D compiled with double-precision floats
• Add support for emission maps
• Fix direction and lens view vector for directional lights
• Do not assign empty TransformBlendTable if a Geom does not have a transform_blend column

Viewer

• Improved default camera position and view
• Add work-around to make lights from the model work
• Upgrade to panda3d-simplepbr>=0.6 for emission and occlusion map support
• Shortcuts added to toggle various render features:
  • n: toggle normal maps
  • e: toggle emission maps
  • o: toggle occlusion maps
  • a: toggle ambient light

Other

• Add --version flag to CLI
• Use GltfLoader.global_settings if gltf_settings is None for patch_loader()

v0.6

Viewer

• Toggle wireframe view with w
• Toggle textures with t
• Dump scene graph to standard out with shift-l
• Dump analysis of the scene graph to standard out with shift-a

Converter

• Fix an issue where morph targets would no longer be bound after saving and loading to model cache

v0.5

Converter

• Add --no-srgb option to skip making sRGB textures (not spec-complaint, but may be useful for some workflows)
• Add options to copy textures
• Add support for morph targets and animations
• Add support for multiple meshes using the same skin
• Add support for skeletons with multiple root bones
• Fix some transformation issues with characters
• Fix color of fallback normal map
• Fix texture stage order (make it deterministic)
• Fix fallback textures not getting saved to BAM files

Many thanks to @el-dee and @rdb who did most of the work for this release!

v0.4

Converter

• Faster loading of bin files
• Support loading supplied tangents
• Calculate tangents if they are missing
  • NOTE: this is still WIP and not spec-compliant
• Support loading normal maps
• More axis-conversion fixes

• The default camera will now look at the loaded model

v0.3

Viewer

• Move rendering and shaders to a new, separate panda3d-simplepbr
• Updates from panda3d-simplepbr:

  • Multi-sample Anti-aliasing

v0.2

Conversion

• Initial support for KHR_lights_punctual extension
• Fix bad file paths for Python 3.5
• Fix bad file paths for Windows

Viewer

• Do not load models from the model cache
• Support OpenGL 2.1 hardware
