Bones are working differently after exporting into Babylon.js

Questions

Hello dudes,

how to get the same behaving of bones like in 3ds max, please? How can I correct my source code? Of course I tried to work with envelopes and the weight of the points, but I did not achieve the same result, see the video.

@Guillaume_Pelletier our exporter wizard might be able to help here and sharing your model (if possible) would definitely help him repro

Hey,
When you’re moving the bone002 into max, there is a constraint on length, which make the bone taking bone001 as Pivot point. I beleive you had to re-create this behaviour into your viewer part. Translation only will NOT work.

Hello,

this is the problem that I try to set other and other parameters, variants in 3ds max… to achieve the same 3ds max result as in babylon.js. But I did not find a solution :frowning:

Hi, the link recommends making this change:
Bone Tools> Objects Properties> Freeze Length

If I do, nothing will change at all. Still the same problem. This means: In 3ds max I see exactly what I need but after exporting to Babylon.js I have an unusable result.

OK, then this is what i told you on very first response, this is related to viewer behavior, not exporter. This must be done by programming into Babylon JS viewer.
