Transitioning or blending two mesh extrusions

[SomeGuyEight]

I believe I have a solution for my generation. I will generate the mesh with overlap and use a mesh combiner to combine the sections of mesh with overlap. To get smooth transitions, I am going to have transition objects that the splines can dive into. The objects will have "slots" for spline extrusions to target. Then the mesh combiner can trim out all the verts inside and make sure it is all connected. The UVs will be an issue at some point, but... that is a problem for future me

I will share my progress as things develop! Is there a good place to share that stuff? 

Here is a link to the YouTube playlist with the early prototypes.
