So in connection to my LOD research, I stumbled upon a problem. For LOD system to work on terrains (made of several meshes), meshes need to match on the seams/boundaries.
It’s not a big deal when it comes to original mesh cut up into pieces, but when I decimate it, boundaries of each piece change.
In Meshlab, there is a feature that keeps boundaries as they were, and decimate only inside area of the mesh.
Do we have anything like that with Decimate modifier? If not, is there a workaround? Thanks.
P.S. If there is nothing like that in Blender, maybe such feature could be added?
