FBX of multiple actions missing keyframes

Short description of error
The scene appears to only export some keyframes after I add multiple actions. An earlier version of the scene only had an animated camera. In the attached scene I've added animated planes and lights. When I export the FBX and import into MayaLT, the camera only has a few frames keyed.

Exact steps for others to reproduce the error

  1. Import attached scene
  2. Using fbx 7, set Simplify to 0
  3. Crean a new Blender scene and import the FBX
  4. Note that some keys are missing



Event Timeline

Confirmed the issue is present in 3.9.1 of the FBX exporter.

We do not handle user support on this tracker, only bug reports. User forums like or should be used for that matter.

Set Simplify setting of animation options of the exporter to 0.0 to avoid any removal of baked keys from curves (by default, it applies some level of simplification to reduce a bit the size of baked animation curves…)

Hey Bastien,

Sorry I don't understand why you think this isn't a bug, were you able to get the sample scene to export correctly? I have tried setting Simplify to 0 to no effect.

Thanks in advance,

I've updated the steps for reproducing the bug to set simplify to 0.

@Jesse (FreakTheMighty) just tried with your .blend, exporting with simplify set to zero gives me all keyframes (one per frame for the nine loc/rot/trans values) when re-importing FBX file here…

Note that current version of the exporter is 3.9.1, would suggest you try the latest build from our buildbot.

Thanks for trying to reproduce it. As I noted in my second comment I did test on 3.9.1. Strange that its working for you, let me investigate more.

I’m sorry, but we cannot investigate an issue we cannot reproduce, so will archive this report until someone can give enough elements to consistently reproduce it. Thanks for the report anyway.
