[mecanicus]

 Hello,

Regularly I have this error t shown during an export with blender. I need help to understand and correct my method of work

 

File "C:\Program Files\Blender Foundation\Blender\2.77\scripts\addons\babylon-js\json_exporter.py", line 100, in execute
    mesh = Mesh(object, scene, nextStartFace, forcedParent, nameID, self)
  File "C:\Program Files\Blender Foundation\Blender\2.77\scripts\addons\babylon-js\mesh.py", line 43, in __init__
    self.define_animations(object, True, True, True)  #Should animations be done when forcedParent
  File "C:\Program Files\Blender Foundation\Blender\2.77\scripts\addons\babylon-js\f_curve_animatable.py", line 39, in define_animations
    animationRange = AnimationRange.actionPrep(object, action, False, frameOffset)
  File "C:\Program Files\Blender Foundation\Blender\2.77\scripts\addons\babylon-js\animation.py", line 74, in actionPrep
    return AnimationRange(actionName, frames, frameOffset)
  File "C:\Program Files\Blender Foundation\Blender\2.77\scripts\addons\babylon-js\animation.py", line 33, in __init__
    self.highest_frame_in = self.frames_in [highest_idx]
ERROR:  list index out of range

@mecanicus : What version of the exporter are you using?

And posting your.blend file would help, so that it is possible to see what you are trying to accomplish.

cheers, gryff

The version ef the exporter is 5.4.0.

I lost the file at the origin of the problem.
When the problem will appear again I shall join the file.
However, I noticed that the error arrived  when I deleted animations. In fact they were 
Not really deleted totally, since in the outliner of blender I purge "Orphan Data".
But I do not know if it really has something to do with the error that I had.

@javalang Thank you for the links, I think that my problem comes a lot of deletion of the animations. The future will say it.

Cheers
