I would like to create a complex animation in which two rigged objects - human head models in this case - merge together as they float next to each other with a similar effect that metaballs have on each other.
Is this possible in any way? I'm trying to find the best way for the skin to pull out from the parallel side of each head and have them merge (With the merged skin materials being seamless), similar to a metaball interaction but with a detailed skin material. The only example I can think of which is along the lines of what I'm aiming for is the split-face scene in The Thing (2011) (Very graphic) at the 2:20 mark. (I'm not aiming for this much realism of course.)
Like that but with the heads floating and magnetized to one another. I'm also hoping to have the faces animated on their own before the merging/smashing together takes place so they'll be rigged but this question is only regarding the mesh & material merging effect specifically.
As far as I know, you can't model and animate metaballs with as much detail and variation that a human face requires or convert part of a mesh into a meta object so would this work by keyframing the skin meshes towards each other in a stretching fashion then merging them into one mesh at the desired frame?
