I posted the original of this question in the Unity support section a week ago - but got no response. So I am reposting it here as there seem to be many Blender specific questions in this section of the forum.
I've been using Unity for a couple of months and want to create a lipsync animation with shape keys. I don't have the money for some of the commercial packages but I found Metamorph which seemed to be a useful little package for Blender/Unity and shape keys that was created by FoolishFrost/Rezzable Inc
I created a simple head (2 bones - neck and head), added one shape key(talk - mouth open) and created a simple animation - head turns (head bone rotation) and mouth opens/closes(shape key) that works fine in Blender. I used the Blender 2.58 MetaMorph plugin to create the DiffMap shape key image and the 72 frame animation file. I exported the head object as an fbx file. Everything seemed fine.
However, when I set the files up in a Unity scene the only animation I get is the head turn - no mouth opening and closing. There are no errors in the console and everything seems to be loading (I turned on verbose in the Metamorph script).
I added the key frames in the Blender FCurve editor - and this is the one difference between my creation and the MetaMorph demo - see the attached image. Is this the problem? Were the keys in the Charon Demo added in a specific way? (I'm new to using shape keys in Blender - though I have used bones in the past for animations.)
As additional info, I am using Blender 2.61 and Unity 3.4 and the MetaMorph 2.58 version of the plugin.
If anyone can help it would be much appreciated as I have been tearing out my hair for several weeks now!. I have zipped all the files - the blend file, the fbx file, the MetaMorph diffusion map and animation text file and placed them here:
Thanks in advance for any help - which is gratefully appreciated.
