How do I morph between unrelated meshes I have 5 meshes that are "unrelated" - they're reasonably complex shapes (derived from medical imagery) stored in separate files created by a 3rd party program and imported into Blender.
I would like to morph from Mesh 1 to Mesh 2, to Mesh 3, and so on.

I've seen various answers on here with "ShapeKeys", but these only appear to be for altering the same mesh manually, that's not an option here.

Is this possible in Blender, and if so how?
Is your medical imagery made only of vertex (no planes)? If this is the case, you could morph one to another by using a particle system.


add a particle system to each object, with the same number of particles
create one additional object with the same number of particles
add Physics > keys in the last created object's particle system, create a key for each of your medical imagery objects.


Here is a complete tutorial about this.

Hope it helps!
