Customizing "GvrControllerTooltipsSimple"

This high performance version of the tooltips seem good, but I'm quite stuck trying to customize them.

• I can't seem to open the FBX models in Blender because they are not in the 'right' format. Has anyone converted them successfully? The default model is only useful if you want all four tooltips. If someone could upload or send a converted version that would be really helpful.
• I can't work out how you edit the tooltip texture in Photoshop - it seems like the text layers are supposed to be in the alpha channel too but this seems to be beyond my level of Photoshop knowledge!

Thanks

 

DM me and I'll convert FBX for you from Maya.
