I have been trying to export a sequence of shape keys that I imported from an .mdd file using the .gltf file format in Blender 2.80. I defined the sequence as an action in the shape key editor and checked sample all animations in the exporter, but when I import the created file back into Blender the shape keys are there but the animation is not. Any ideas what could be going wrong?
I checked that file, I did that steps: exporting .mdd file, creating a new cube and imported previously created .mdd file. All works fine and animation works.
