Smoothing/blending a joint between two meshes I'm modeling a car, but I don't want to add any polygons. I don't need to (I'm trying to have a nicer mesh) so I've got two separate pieces here. Unfortunately this doesn't give me the curved effect, as in the picture below.

I was thinking to fix this in a normal map, but I'm sure I've seen tools for doing this specific thing, and I just can't recall how I saw it done (whether it was in a texture map or not).

I wasn't really big on the solutions, I did find for this here.



Here's a picture of the wireframe. 


I could model this, I just don't want to do it that way, I'm sure there's an alternate way.
As it turns out I can make this piece into a 'plug' with MeshMachine and place it on my mesh with the additional smoothing in the corner modeled onto that plug.

Just waiting for the 2.8 version
