FBX Animation Action Export Issue
Open, ConfirmedPublic

Broken: 2.79b

Short description of error
I have a object in Blender that is rigged with 3 animations in the action editor. When exporting via FBX binary, only 2 of the three animation actions get exported. When exporting using FBX ASCII, all animations are exported correctly. Also, with ASCII, I've been experiencing issues where ASCII will export incorrect texture file names.

Exact steps for others to reproduce the error

  • I'm not sure if there's a better way to do this, but I've been converting .fbx binary files to JSON with this (command: conv.exe toConvert.fbx output.g3dj) to inspect the files.
  • Export the files using the built in Blender to FBX export function (binary). Convert to .g3dj using the utility, or inspect with another method. The FBX file does not contain all animations present in the .blend file.
  • Export the files using Blender FBX ASCII. Inspect the ASCII file using Notepad, all animation actions should be present (in this case: engage, disengage, fire).

Please:

  • Ignore ASCII, this is deprecated and no more maintained at all (and to be removed soon from the codebase).
  • Give us exact settings you are using for your FBX export.

… And making twice the same report is not a good idea either. Not at all. We already have way too much reports to handle! Suggest you think about it twice next time.

@Bastien Montagne, sorry, I tried to report the bug through Blender with the built in report button in the add-ons and also through the website. I didn't realize they connected to the same thing. Won't happen again.

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.

@Will Davies (x_tech) Uuuh indeed… Force Start/End Keying should prevent that behavior, will check.
