lucas veber (lucky3) added a comment to T56883: Incorrect bones matrix calculation when exporting to Fbx.

Glad to hear it's working fine in 2.8, sure I totally understand 2.79 is no more developed.

Thanks for the report, but even though I can confirm the issue in 2.7x, I cannot reproduce with 2.80… All efforts are now on 2.8, so I do not intend investigating further *why* that weird glitch happens in 2.79.

You're right, I forgot that the gltf exporter wasn't shipped with Blender — I've now reported at https://github.com/KhronosGroup/glTF-Blender-Exporter/issues/306.

I could only guess about what is happening exactly but this looks more like a bug in the addon.
This addon is not shipped with Blender, right? (I'm confused right now^^)

Jesse (FreakTheMighty) added a comment to T54050: Camera focal length animation not importing.

Not sure why, but focal length keying worked for me in Blender Version 2.79 (2.79 2017-09-11, Blender Foundation), but does not work in Version 2.79b (2.79b 2018-03-22, Blender Foundation).

lucas veber (lucky3) added a comment to T54118: FBX export of armature using Spline IK looks very wrong.

The main problem in this scene is the cyclic dependency, that is likely introducing issues when it comes to animation baking.
It's a common problem with Spline IK constraints. You can open the Blender console to see the error log, and when moving the rig bones, there's also a one frame lag which is due to the cyclic dependency issue.
The dependency graph is being re-written for Blender 2.8 to avoid this (as far as I know), for now only this kind of rig setup should be used with IK Spline constraints:

Seems like a scale/stretch related issue? If so, it's not a bug, Fbx does not support it: the scale value of each bone inherit the scale of the parent bone.

John Nagle (nagle) added a comment to T56721: COLLADA exporter does not emit layer information..

Fair enough. Currently, SL viewers currently do not recognize layer info in COLLADA files. They want each layer in a separate file.

Gaia Clary (gaiaclary) added a comment to T56721: COLLADA exporter does not emit layer information..

I already stated that we can add the layer attribute to the Blender collada exporter. I explained how i would do this and i explained what challenges i see to get this done properly. I also stated that i will add the layer attribute. So your request for adding this feature has been well heard and will be provided some time in the near future.

John Nagle (nagle) added a comment to T56721: COLLADA exporter does not emit layer information..

I believe that your request actually is much better placed in a separate addon that handles SL collada management in some way.

Gaia Clary (gaiaclary) added a comment to T56721: COLLADA exporter does not emit layer information..

The enhanced Layer management is an addon. However, we can not add a dependency between the collada exporter and any addon, so for the blender collada exporter we still must limit the features to what default blender has to offer. For blender 2.8 i do not know yet how the layers will be organized. so i need some time to look into this (which i will certainly do before 2.8 is released).

John Nagle (nagle) added a comment to T56721: COLLADA exporter does not emit layer information..

If the standard Layer Name addon is enabled, Blender has named layers, and the names appear in the Layer tab. By default, the names are "Layer0", "Layer1", etc., The user can rename them in the Layers tab.

Gaia Clary (gaiaclary) added a comment to T56721: COLLADA exporter does not emit layer information..

yes, this is not a big issue to add to the collada exporter. Although the layer names would then actually be taken from the layer indices "0", "1", ... "31" I am not sure how we would support the creation of named layers here (blender does not support named layers in 2.79).

I think I solved this issue, FBX export apparently doesn't export animation actions with unused key frames in them. It'd be nice if it'd output a message displaying this.

Bastien Montagne (mont29) assigned T56574: COLLADA Exporter Transform animation by Euler angle is not reflected to Gaia Clary (gaiaclary).

Did not check in detail, but I would guess that’s because Collada uses matrices, which would loose the 'multi-turn' angle, unless you add enough intermediate keyframes?

mario (ziomario) added a comment to T56597: mesh + armature exported in FBX format (7.4 binary or 6.1 ASCII) and imported in NUKE 11 does not work well..

I think that it not necessary to look into the code as first thing to check. Maybe I used wrong configuration on the settings of the FBX panel,or it's necessary to use a "special" combination of settings,that I don't know. The best solution I think could be to make some attempts by the cross users,users who uses/know blender and nuke. I think that it worth trying before to close this post. If It was not strictly a bug,it was very close to be a bug,because each combination of setting should produce a different kind of effect,but since it could work only in some circumstances,it could be a bug.

You’ll have to give proof that issue is from Blender side, not from Nuke side first… afaik meshes are pretty reliable in our FBX io addon. Not our job to investigate that kind of issue, especially not with a closed-source software we don’t have access to.

ok for the armature,but not good for the mesh. Nuke should import correctly the FBX file format.both in 6.1 ASCII and in 7.4 binary format. If it does not do it correctly,it's a bug of blender. So,I suggest to re open this bug. And anyway,the question deserves to be deepened,not closed on two feets.

Thanks for the report, but this sounds more like user support than bug to me - we don’t even know whether Nuke supports rigging at all, even less if it can import it correctly from FBX…
