Could you provide an example of what you are trying to achieve? I do not understand why you are trying or wanting to use shapekeys with bones? Typically you would animate keyframes of your bones and this would control the animation of your mesh. Now with that said…I guess I could come up with some wild ideas…but your next questions has me more perplexed…you are wanting to set shapekeys animation with bones…. So in this case you have a object that you have control over with shape keys….then you are adding a bone to that shapekey controlled object and wanting the bone to influence the shapekey object in addition to the shapekey control? My thoughts are you have a sphere and you want it to transition to a cube…so you create a shapekey system…now you want that shapekey to have bones so you can bend it?

Ok…so giving this some thought..I played with a simple cube…and edit two vertices making a simple shape to use as the shapekey. I keyframed the shape key value at 0 at frame 0 and 1 at frame 48. I then created a bone and parented the shapekey to the bone….create. With the bone active I animated the rotation in the X axis… frame 0 – 0 degrees and frame 48 – 360 degrees. Just to test out if you can create a shapekey animation then attache that animation to a bone…and the answer is yes you can and more importantly it works just fine in Verge3d using Blender 5.1. I didn’t test other versions.

You can see a demo of it here: https://v3d.net/1hra
Full project including blend file located here: https://v3d.net/1hrb

Is this what you are trying to do?

Seems like it’s a bug, we’ll fix it in our next release, but for now you can export your scene from the first frame, it helps to fix the bug.
