I've found DMXs usually have issues with animations, but exporting a DMX and then an SMD, and using the SMD export as the source for the animation has worked for me, but not for this.

Thanks for the suggestion, I'm not sure how to turn each piece of glass into having its own bone in one model. I tried 'joining' the glass pieces but that broke the animation.

I'll look into it though, and if anyone else has suggestions I'd be interested to hear.

I have a pane of glass with an animation of it 'shattering', using the rigid body phsyics. I have made it, but what is the proper way of exporting it?

This is for Source 2 (specifically SFM 2). I'm using Blender 2.9.
