Colin Knueppel (ColleyKnu) added a comment to T47043: Importing an fbx skeletal mesh from Blender into Unreal Engine 4 results in bones being too small to create Unreal physics asset. Requires scaling workaround..

This task is 6.5 years old. Maybe fixing the fbx exporter isn't possible with the licensing issues as they are. What about a hack export to Unreal option that very specifically modifies the animation data for Unreal exports so that the armature isn't shrunk?

Colin Knueppel (ColleyKnu) added a comment to T99075: Blender Scale problems when export to Unreal.

It's directly related to Unreal. I don't know if it shows up in other programs, but I can link you to about half a dozen different forum posts on Unreal sites that are trying to figure out this problem. The issue is very specifically that the blender fbx exports import into Unreal with the skin at one scale and the skeleton at another, and this causes particular problems with physics and socketing attachments in Unreal. This bug report has a very specific scope, unlike the other generic fbx card (that hasn't been fixed for several years).

Pratik Borhade (PratikPB2123) removed a project from T99075: Blender Scale problems when export to Unreal: BF Blender.

Epic's Unreal is quickly growing again in the games industry and increasingly used in television, short film and movies. I worry that this should be treated as it's own bug, because this is a very specific workflow that at least tens of thousands of professionals are regularly having to navigate around. A specific solution to this particular workflow may be quicker than addressing the larger issues of the FBX import and export. Considering all that, and that Epic is a corporate level sponsor for Blender, is it that big of an ask that this get treated as a task with its own priority (That other task is almost 3 years old, btw)?

And apply transform did not work.

@Bastien Montagne (mont29) Hi, can you comment on this? I don't see any reason to relate this issue with Unreal engine since issue is related to FBX import/export

@planaria megatron (planaria) What I meant is that you should inherit full scale for all bones and correct their keyframes afterwards to compensate for the missing scale, which is manual work, but is the only workaround I can think of right now.
So in general, don't use "inherit none scale" if you will be exporting to FBX for now.

As a Pipeline developer for both Unity and Unreal this issue is a bit non-trivial for the reasons stated above and I'd love to see a way for us to manually set Animation names by ourselves for each Action.
In games we usually reuse animations across many rigs/characters so having an Animation's name ALWAYS linked to its Rig can cause confusion and pipeline problems.

Mat Brady (matbrady) added a comment to T70161: FBX I/O Imports and exports objects with wrong scale transform.

I discovered something about the scaling issue. Even though Blender can display a rig at 1.0 scale, (with the scale having been applied) it can be a false 1.0 scale, because the FBX Exporter will be reading something different and export the same rig but at a scale that the Exporter is reading (where ever that info is. From I don't know where). That's why the scale issue was happening with me.
I experimented and found a solution (which I posted here: https://blender.stackexchange.com/questions/265519/fbx-export-scaling-issue-into-unity-solution ).
Essentially, I proved that applying a scale through normal means is not enough for the FBX Exporter, and to solve this I needed to make this rig (which had the false 1.0 scale) a Child Of an empty (using the Child Of constraint) knowing that the empty will have by default a true 1.0 scale.
I could then export the rig at the correct scale (adopting the Empty's true 1.0 scale).
I then applied the Child Of constraint, transferring the true 1.0 scale from the empty to the rig, and could then safely delete the empty.
This is a work-around, but it's also proof that the FBX Exporter is reading different info to what Blender is displaying.
I hope that helps.

exported bones are now significantly reduced, yet some remains, I'll try to investigate why

FYI : I have the same issue installing MY addon while the problem comes form the official Anim Extras addon
(workaround : disabled animextras - install my script - enable animextras)

There are 118 bones in this file, it could be simplified more.
What is the non-deforming bone to analyze?
The ones I identified have deforming children.

I checked the system for malware and nothing happened. The system didn't detect any malware and the issue still doesn't seem to be fixed.
