[SOLVED] babylon.exporter too much frames

[javalang]

Hi all,

I'm using blender-BJS-Exporter 5.4.0 and have a blender scene with a keyframed animation starting from start Frame:0 to Frame:120. Unfortunately there are much more frames exported than expected (up to 640 but with gaps). It seems the scene is looped a second time but with some garbage and some gaps inbetween.

I'm new to blender but I'm quite sure to have a consistent scene.

Any ideas?

Thanks in advance

You are probably using the JSON / .babylon exporter, but I can explain using the source code generating exporter, Tower of Babel.

You are doing non-skeleton animation, so you get animations for position, then rotation, then scaling.  You are not scaling in your case, but this is really not detectable.

You do have 3 actions in your .blend, so the # of frames are cumulative.  These 3 animation ranges get created.  The gaps are just for sanity of separating where each action starts / ends.  If you are only interested in Action.001, then delete the others.  The exporter does all.

this.createAnimationRange("Action.001", 0, 120);
this.createAnimationRange("Action.002", 130, 250);
this.createAnimationRange("BezierCircleAction", 260, 380);

Also, if the rotation or position is linear, you can remove frames in the middle, I think & save some space.

@JCPalmer thank you very much for reply.

This is the problem, I have only  one action in my blender file... so how to delete the others? I baked an animation from a follow path constraint...and deleted the curve afterwards . Maybe garbage in the blender file!

My target scene will not be linear, it's only a test, but thanks for the hint.

Yes I've installed this plugin, but I don't know to use it and I red something about that this software was replaced by exporter?

Can you drop me some lines how to use?

PS: Oh I see, there will be a file.js created...

Thank you again

OK, problem found, it was garbage in the blender file. Blender has some difficulties in deleting animation data, now after "real" deleting, saving and reloading the right count of frames are finally  generated,  see delete-action-from-list
