How To Stop UE4 From Changing the Vertex and Triangle Count When Importing?

Unreal is very particular about how it arranges vertices and triangles. It will split vertices along all kinds of material attribute seams.
You cannot use the default unreal import path if you can’t deal with this.

I’m assuming that you’re blending between these to create a person-to-wolf morphing animation?
If so, you could perhaps create a morph target that takes the first mesh to the second mesh. You can then animate this morph target between 0 and 1, and then swap out to the new mesh when the morph is done. If you try to skinned animate at the same time, that might not work as well, though.

Thank you for the help. My approach really cannot rely on using Blendshapes. I was actually able to get this working very in Unity. If there was a way to figure out what causes UE4 to split the vertices that would help out immensely. One of the models was able to import properly so I am working on the other one now but its an hassle. At this point I need to make changes in my 3D application like 3ds Max so UE4 won’t split the normals but its difficult finding out what is causing it.

Here is a video of what I am trying to do in UE4 after doing it in Unity:
