gltf glb animation export

WendyLuvsCatz

I am stumped, how does one export an animated glb or gltf file from Blender?

I have a perfectly good Alembic import of a Dforce clothed animated figure in Blender thanks to TheMysteryIsThePoint's Sagan which I want to export to Twinmotion (or view in Windows 10 3D viewer) but Blender only exports a static file even though I checked all the different animation options.

I am sure I have done this before with gltf files I downloaded off the web

(Twinmotion did not do animated imports back then only Unreal Engine did)

but for the life of me cannot figure out what I am missing

sadly all my other gltf files were on my deceased external harddrive so cannot test those in Twinmotion or the Windows viewer for comparison, not gotten as far as setting up Unreal Engine since my Windows reinstall yet either

I cannot see any keyframes on the timeline even though the figure is moving so wondering if there is some action I need there? Does the animation need to be baked some way?

( I tried cache file in view as assumed abc would have keys for that but what do I know)

Oh nevermind, Twinmotion only supports bone animation apparently not mesh deformation
