I'm very new to Blender and I'm play around with the armature deform. I'm try to animate the opening of a box.

The animation look properly working in pose mode.

Animation In Blender

The issue is when I export the project in glb format and try to open it with other software (like Reality Converter) I get the animation totally wrong.


For sure is due to some mistake on the application of the bone / armature, but I really don't know what to correct

How can I fix this?

    $\begingroup$ maybe you should create another bone for the rest of the object? $\endgroup$

    $\begingroup$ Without your file provided, we can only guess, but as @moonboots says, this may be due to fact that you only use one bone that acts like a root, maybe you should make root bone under this bone and rotate the bone that is attached to root bone (maybe it will solve this issue $\endgroup$

Create an armature with 2 bones: Lid and Box. Parent Lid to Box. Parent the box object to the armature with the Empty Groups mode. Select the vertices that are supposed to be controlled by the lid bone and go into the Object Data panel > Vertex Groups, select Lid and click Assign. Same thing for the box vertices.
