1 thats not true... threejs can import Fbx without any bones, rotated or otherwise

example: this Mixamo model has had custom hair added then converted to the old [1974] Fbx standard which loads in both Blender or 3js

2 what i recomend is you stop using 3js until you have a solid understanding of json... even then its not a great tool because so few people want to use it

 

learn Blender first that will give you the basics and works on almost any system then if you need to go pro move onto Iclone which is Windows only & $ but works right out of the box and is much better supported than 3js

 

3js is a web code based display... thats its strength and weakness

not many people want to learn the code and most clients systems will block web based code because they feel its not safe

i see user error

what you actually want is the main bone zeroed i.e, the one every other bones links to... but setting every bone to zero means they try to be in the same spot i.e, your software just did what you asked it too and this has nothing to do with Mixamo

 

1 what software are you using to display/ use the model? [the way to do things depends on what you are using]

2 why do you want bones set to zero... is this something your teacher told you to do or you just trying to follow a tutorial?

Thank you for your response. I really appreciate it!

my anwser to your questions:
1.I'm using threejs to display model with pose. threejs has no method to apply pose or load model with no init bone rotation.

2.I have every bone with calculated rotation, need to rotation to every bone. so the pose can show on web. If i done this, anyone can use the model they like generated by mixamo.


I have some old models download on mixamo, the model has no rotation so i can pose it successfully.

please download xbot-ok-ascii.fbx for no rotation model and marker_man_rotated_ascii.fbx for recently downloaded with bone rotated. sorry for upload it failed. The below picture show old xbot model download from mixamo with no rotation.


what software did i try to import-then-export fbx to delete all bone rotation but has no result:
maya, blender, unity

 

i would be grateful if you has any suggestion. thanks!
