Morgan Fraslin (kevar) added a comment to T54071: [FBX Import] Wrong scale on imported objects.

Hi, please find here a much lighter file. I'm not able to reproduce the issue with a scene built from scratch so I've simplified as much as possible the current scene. I hope it will be ok.

Nick Fox-Gieg (n1ckfg) added a comment to T52417: Cannot seem to export Vertex Color with Alembic for Maya nor Houdini.

Here's what I've got so far...it builds successfully and exports valid Alembic files, but abcls doesn't find the mayaColorSet=1 flag so I'm still doing something wrong.

Alembic::AbcCoreAbstract::MetaData md;
md.set("mayaColorSet", "true");
OC4fGeomParam param(prop, name, true, kFacevaryingScope, 1, 0, md);

Implemented import & export of camera focal length in FBX now, so will re-assign to @Sybren A. Stüvel (sybren) for the Alembic part of it…

Bastien Montagne (mont29) triaged T54071: [FBX Import] Wrong scale on imported objects as Incomplete priority.

I suspect this file uses advanced FBX features we do not support… but hard (impossible) to tell with such a big fat FBX, please try to reproduce same issue with dead simple file (like, only a few cubes, without any addition like materials, textures, animation, etc.).

Gaia Clary (gaiaclary) added a comment to T45687: COLLADA exports animations values for Location in world space instead of local space.

I have started a rework of the animation exporter. The fix in D3070 already solves the issue, but it needs some refinement and further testing.

Nick Fox-Gieg (n1ckfg) updated subscribers of T52417: Cannot seem to export Vertex Color with Alembic for Maya nor Houdini.

OK, progress--I can build Blender from source with Alembic enabled. Next step, @Dario Seyb (daseyb) says for Unity he used the following to add the Maya color set flag:

AbcGeom::MetaData md;
m.set("mayaColorSet", "true");
m_colorSet = AbcGeom::OC4fGeomParam(m_scheme.getArbGeomParams(), “Cd”, true, AbcGeom::GeometryScope::kFacevaryingScope, 1, m_tsi, md);

Could you help me adapt this for Blender?

@Nick Fox-Gieg (n1ckfg) I think a good place to put that would be in write_mcol().

If I wanted to recompile Blender's Alembic export module with the mayaColorSet=1 flag added, where in the source should I look?

The FBX exporter does it similar to this:

Sure thing. Actually it's the same issue in Maya in case you're able to test it. Haven't tested with 3dsmax but i'd assume it may be the same.

Bastien Montagne (mont29) closed T53828: Export in ASCII FBX 6.1 as Archived.

Yeah, final word here is that FBX6.1 has only been kept for a few specific use cases where it was better/easier to use than binary 7.x. But it is not maintained anymore, and doomed to disappear soon. Supporting one version of that mess is already a nightmare, we cannot afford to support older versions too. :)

Joe Williamsen (jwilliamsen) added a comment to T53821: FBX Import Fails to Import (some) rigged FBX Files Correctly.

I think it might have something to do with Softimage's bones having "roots" and "effectors" by default. If I export the FBX without the roots and effectors, I get a different result - still broken, but different.

Bastien Montagne (mont29) added a comment to T53821: FBX Import Fails to Import (some) rigged FBX Files Correctly.

For some reason, this FBX generates two different armatures when imported in Blender, which make a mess in binding (if you set both armatures to Rest pose, the mesh is not weirdly deformed anymore).

I dont have maya or 3ds max. this fbx is ok with windows 3d painter and daz studio. I tried to open in daz and save again to work around but it introduced some daz studio things not needed. I suspect that the reason it cannot be opened in blender is that I put chinese character in file name when I saved it in marvelous designer. Marvelous Designer uses fbx sdk, it should be ok with maya and 3ds max in my opinion.

Regarding OBJ file, I guess we have no issues here because we do not have the MTL file associated with it (its path is the only textual info in an OBJ file I think…).
