My issue is that I exported my little maze thing out from Maya to FBX making sure the right boxes were checked, etc. What I did was animate the “bar” parts of this maze to expand like “lungs,” like the section under the mouse in my screen shot. Instead of animating they stay stationary. I also notice some key frames are on the slider yet no action occurs.
I am repositioning verticies in Maya, and key frame everything to mak esure it is not left out of the process.
My understanding is that you cannot use vertex/edge/face animations in Unity. You can move objects, and drive skinned meshes with bones, but not what your trying to do.
What your trying to achieve is done through the mesh scripting interface, but thats a whole other kettle of fish.
Have a good look at the procedual examples.
In this case, what might work is modelling a static scene with walls in place, then animating the models y-scale, from a really low value to whatever, so it goes from flat to 3d. But thistime keyframe the object in object mode.
