Mesh Cache Modifier Broken in 2.66?

Support Animation and Rigging

Hi All,

I thought I would try out the new mesh cache modifier but it seems to be broken.
My understanding of this new modifier is that it can be used to play a series of mesh objects over time.

Every cache I point the modifier to generates a

Vertex count mismatch
error.

Here is my workflow.
In a new scene, delete the Cube and create a sphere.
Export a single frame as MDD or PC2. (they both fail to generate valid data for the mesh cache modifier)
Open a new copy of Blender and apply the mesh cache modifier to the default cube.
Browse to the newly exported MDD or PC2 file and the modifier reports the above error.

Does this code actually work, or is it just broken in 2.66?
Is the problem in the exporters or the modifiers?

The vertex count and vertex order need to be the same for your object and mdd source for correct modifier playback

For example, use the attached zipped mdd with the default uv sphere. Combines a simple keyframe object rotation and a shapekey change.

I see, so I need to apply the mesh cache to the first object in my mesh sequence, not the default cube. (Unless my animation was based upon the default cube).
