Miraculous gum

A short video demonstrating the use of blender in aligning teeth. The gum is able to move and s t r e t c h.... This is amazing because most orthodontic software is very limited to gum movements. Once there are overlapping vertices, models do not print. So blender is amazing. I am looking for some help though with exporting animation to mobile phones. I use fbx review, but morphing meshes do not seem to work. I've tried alembic files which work, but no colour...grrr. Any help?
