This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.
Each class XML's schema conformance is also checked on GitHub Actions.
Using codespell 2.2-dev from current git.
Added `misc/scripts/codespell.sh` to make it easier to run it once in a
while and update the skip and ignore lists.
(cherry picked from commit 1bdb82c64e)
Fleshed out the "Optimize Mesh" options found in the mesh import UI
Gave a checkbox to every vertex attribute that can be compressed
Surfaced option to enable/disable Octahedral compression for
normal/tangent vectors
Also surfaces the vertex position compression option which previously
inaccessible because the defaults did not compress vertex positions
Supports all current importers (obj, fbx, collada, gltf)
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
Implement Octahedral Compression for normal/tangent vectors
*Oct32 for uncompressed vectors
*Oct16 for compressed vectors
Reduces vertex size for each attribute by
*Uncompressed: 12 bytes, vec4<float32> -> vec2<unorm16>
*Compressed: 2 bytes, vec4<unorm8> -> vec2<unorm8>
Binormal sign is encoded in the y coordinate of the encoded tangent
Added conversion functions to go from octahedral mapping to cartesian
for normal and tangent vectors
sprite_3d and soft_body meshes write to their vertex buffer memory
directly and need to convert their normals and tangents to the new oct
format before writing
Created a new mesh flag to specify whether a mesh is using octahedral
compression or not
Updated documentation to discuss new flag/defaults
Created shader flags to specify whether octahedral or cartesian vectors
are being used
Updated importers to use octahedral representation as the default format
for importing meshes
Updated ShaderGLES2 to support 64 bit version codes as we hit the limit
of the 32-bit integer that was previously used as a bitset to store
enabled/disabled flags
- `Texture::~Texture` expects `props` to be dynamically allocated.
- `GetPropertyTable` returned a pointer to an existing `PropertyTable`
but is expected to return a newly, dynamically allocated one.
- `PropertyTable::PropertyTable()` suggests that an empty `element`
property is valid.
fix#46876fix#45573
(cherry picked from commit 09bda3f140)
Fixes several instances of error: 'const' type qualifier on return type has no effect [-Werror,-Wignored-qualifiers]
This looks like it was fixed in 6607fc7da9
when FBX was merged into the 4.0 master branch:
"- fixed const correctness with C++/C version change"
Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆
(cherry picked from commit b5334d14f7)
limitations:
- always has to use generated normal's.
- some animations won't be compatible (yet)
Co-authored-by: Rémi Verschelde <rverschelde@gmail.com>
Better materials:
- default values will no longer trigger things like emission,
clear coat being enabled etc incorrectly, mostly importers misunderstand
this value, a value of 1 is not actually enabled emission, it must have a
non zero setting other than emission value for the emission flags to
actually be enabled correctly in our engine #42386
- lambert materials are warned against significantly,
do not use Lambert in Godot, use a PBR material like Ai Standard Surface
(it's like going from low quality to high definition in terms of output
in scenes and on assets)
- roughness values are calculated correctly in this version
Fixes for normal's array - some normal's from some files were dropped and
generated, this is now fixed.
- FBX indexing for items with (-1) index, for normal data is supported,
this is super helpful at increasing our range of compatibility of
FBX meshes.
Fix bone rest data **no longer requiring go to bind pose in Maya and various applications**
- Partial fix for #43688
Validation tools added for validating large projects
Provide package name, vendor and FBX vendor in the log.
Implemented metadata properties so we can read extra document
info required for bug reporting
**FBX 2011 (version 7200)** is unsupported now,
you must re-export your file in Maya or Max to upgrade the file format.
Fixes skin bind poses being generated based on node xforms in the scene
Fixes duplicate bones being added to skin and prevents add_bones from
registering skeleton bones it now registers skin bind poses,
but this should really be documented in the engine correctly right now
it doesn't tell you this is the case.
- Fixed bug with FBX so we can import material values from the document for PBR when using StingRay (not Arnold *yet*)
- Adds more explicit errors and makes things simpler to read. Has more sanity checks to be sure things are working correctly
- Lazy Properties fixed items not loading due to capital letter errors in FBX parser
- Added debug tools to the materials so you know explicitly what material mapping is assigned to a texture and where it came from. (enable verbose printing to use this)
- Fix broken material mappings and debug entries properly
- Fix make embedded images properly detected
- Spam less errors for unsupported shading models with materials.
Future plans:
- Arnold materials need converted to PBR model, if possible.
This is because a skin bind count must match skeleton bone count, we should make this not the case for 4.0 IMHO as we can reduce the skin size in godot and make the skin surface simpler to process and have less entries :)

This is a complete rewrite of the importer. It will give more deterministic behaviour and has been sponsored by IMVU inc, over 1 year has gone into the development of this importer to remove the burden of the FBX SDK.
This was my project for 1 entire year and I really enjoyed the opportunity to add to Godot.
Along the road of implementing fixes we implemented fbx pivots, animations and inheritance type handling, which in most cases works properly.
We have implemented animation and mesh skinning too this should work out of the box, if there are issues let us know.
It's designed so that you can expand this with ease, and fix bugs easily too.
It can import from Autodesk Maya and import into Godot, with pivots.
There are bits we could polish but for now this is good enough.
Additional fixes made before upstreaming:
- fixed memory leaks
- ensure consistent ordering on mac linux and windows for fbx tree. (very important for material import to be deterministic)
- disabled incorrect warnings for fbx_material
- added compatibility code for /RootNode/ so compat is not broken
- Optimise FBX - directly import triangles
- remove debug messages
- add messages for mesh id, mesh re-import is sometimes slow and we need to know what mesh is being worked on
- Document no longer uses unordered maps
- Removed some usages of &GetRequiredToken replaced with safe *GetRequiredToken() function
- Added parser debugging
- Added ERR_FAIL_CONDS for unsupported mesh formats (we can add these later super easy to do now)
- Add memory debugging for the Tokens and the TokenParser to make it safe
- Add memory initialisation to mesh.cpp surface_tool.h and mesh.h
- Initialise boolean flags properly
- Refactored to correct naming for the fbx_mesh_data.h so you know what data you are working on
- Disabled corruption caused by the FIXME:
- Fixed document reading indexes and index_to_direct vs indexes mode
- Fixed UV1 and UV2 coordinates
- Fixed importer failing to import version 7700 files
- Replaced memory handling in the FBX Document with pointers, before it was dereferencing invalid memory.
- Fixed typed properties
- Improved Document API
- Fixed bug with ProcessDOMConnection() not working with the bool flag set to true.
- Fixed FBX skinning not deforming for more than one single mesh
- Fixed FBX skeleton mapping and skin mapping not being applied properly (now retrieved from document skin list)
- Fixed set_bone_pose being used in final version()
- Fixed material properties exceeding 1.0.
- FBX Document parser revamped to use safe memory practices, and with graceful error messages.
- ScopePtr, TokenPtr and various internal types have been fleshed out to use proper typedefs across the codebase.
- Fixed memory leaks caused by token cleanup failing (now explicit cleanup step, no shared_ptr, etc)
- Fixed bug with PropertyTable not reading all properties and not cleaning up properly.
- Fixed smoothing groups not working
- Fixed normal duplications
- Fixed duplication check for pre-existing coordinates.
- Fixed performance of vertex lookup in large meshes being slow, using lookup table separate to the data for indexing, this reduces import time from 10 minutes of bistro down to 30 seconds.
- Fixed includes requiring absolute path in headers and cpp files using CPPPath.
Bugs/Features wish list:
- locator bones
- quat anim key interpolation (most fbx maya files have euler rotations from blender and maya, nobody uses this)
- some rigs skins scale up when SSC enabled inconsistently per bone
- some skins can disappear entirely
- material mapping needs expanded, but this will be done for 4.0 as it requires rewrite.
Workarounds for issues found until we patch them:
- mesh -> clear skin can resolve most of the bugs above.
- locators can be worked around by removing them before exporting your rig.
- some material properties wont always import, this is okay to override in the material properties.
**If you are having issues or need support fear not!**
Please provide minimal rigs which can reproduce issues as we can't spend a lot of time investigating each rig. We need a small example which breaks and we can then sort the problem. In some cases this is not possible so its okay to privately send models to us via IRC or a ticket and we can provide an email address, we won't reveal or disclose privately sent rig files to any companies, or to companies I work for, they will not be shared, only tested and bugs will be drawn up from the conclusions. Also include identifying information about what you did and how it didn't work. Please file each file separately in a bug report, unless the problem is the same.
This was sponsored by IMVU, and a special thanks to everyone who supported this project.
