Phil Stopford (philstopford) added a comment to T54704: FBX import from modo : blen_read_material assertion failure.

It's reporting as 2.79.3 in the header, so I thought this was 2.79b; I'll ask them why their labeling is misleading. Apologies for the noise.

This is not an official blender version, right? (seeing that it is distributed by Chaos Group)

Just something random my eye falls on (by no means is this any serious review of all of the code): the functions xxx2str seem to be misnamed. They are not converting to strings at all, they are converting to bytes, and thus should be named as such.

Two files for testing. They both are a uv unwrapped cube, however the data is stored in different order.
With the old code, they get different hashes, with the new code, the hash is equal.

Philipp Oeser (lichtwerk) closed T54294: Problem in Duplicate for Alembic object as Invalid.

That's because the CacheFile in the modifier is actually shared (as in: has two users).
Not everything in the modifier is shared (e.g. you could still alter the object_path individually for each modifier).

lucas veber (lucky3) added a comment to T53908: Fbx export: random, weird bones rotation artefact.

While praying for this bug not to be forgotten in the dark, i've simplified at maximum the example blend file (attached) to help. It now only contains one mesh and two bones. When exporting to Fbx and importing in other apps, such as Unity, "bone2" is imported with Rot X = 179.8, instead of -90.
Rotating in Edit Mode bone2 1 or 2 degrees in Blender fixes the issue. However it's not a clean solution, it may happen in other situations. Seems to happen when a bone is making 180 degrees x-axis angle with its parent.
After further investigations with the Fbx exporter code, tracking the exported rotations values seems to output correct values. However it's the way these values are read in other app that is the problem. Likely to be an euler issue, if only Fbx used quaternions...

Michael Chapman (woppin) added a comment to T44407: FBX: UE4 -> Blender -> UE4 makes armature animations of UE4 broken.

I don't know blender very well so I don't really know how it works under the hood, but there's a plugin for blender available on the marketplace called Auto Rig Pro that's able to export a UE4 Mannequin rig correctly, with no retargeting required and the imported mesh can simply select the UE4 Mannequin skeleton.

Philip Holzmann (Foaly) added a comment to T54362: OBJ import - same named .obj entries are appended to one mesh / not extra objects.

I'd say this is not a bug.
The same group name can apparently be reused, and refers to the same group.

  1. the .obj specifications are rather vague and do not mention what is supposed to happen with duplicate names.
  2. ue4 does the same thing with these files.

Ejnar Brendsdal (ejnaren) added a comment to T54227: FBX import adds multiple copies of same material.

Allright here is the conclusion. The bug was on the Rhino side of things and is also solved.
So this issue can be closed and everyone is happy :)

Ejnar Brendsdal (ejnaren) added a comment to T54227: FBX import adds multiple copies of same material.

Hmm... wierd. In my rhino it only imports as one material...
Anyway the discussion has moved on to the McNeel forum.
As far as that goes it could seem to be solved in the latest version of Rhino.

Hmm... Interesting.
I did not know you could JSON-ify FBX files.
I will contact McNeel and hear what they have to say on the matter.

Thanks for the report and file. I can confirm there are two materials in Blender, but… it’s because there are two materials in FBX file!

There is probably something in how materials are stored… Can you please submit rather a two-objects-using-same-material FBX from rhino? One thousand one does not add anything here, except tremendous amount of noise in a huge file, making it impossible to analyze. :P

I don't see why something like that should be an addon instead of a core feature in User Preference - Editing or somewhere.
