Blen4web and Alembic animation not playing I created alembic files from different 3d software (from iclone type ogawa for Blender).

When I import the alembic file into Blender 2.78 (together with the blend4web SDK latest release) and play the timeline the animation runs smoothly, but when exporting the scene the json or html files do not play the animation.

The Problem

How do I transfer the animations from alembic to mesh so it can be played after the scene is exported in json/bin or html format ?

I also tried using an add-on, but it didn't work. Here is the link to animation jointer.

It helps joining all the animations in one and creates keyframes per frame animated plus other features.
You might want to try baking your vertex animation with this dedicated tool available in Blend4Web:
