blend4web and unity3d - normals and shape keys

hi i'm using blend4web to edit my model normal's but i'm having a weird bug with unity3d
when i import my .blend file into unity3d and my model having shape keys unity3d ignore the blend4web normal's edit
if i remove the shape keys unity3d recognize the blend4web normal's edit

if i export an fbx everything works fine but i will prefer to be able to import .blend files

any ideas on how i can get it to work?

Hello!
I think you should report about this behavior on unity forums. It seems that it just shortcoming of unity .blend importer.
