![]() I found some old screenshots from the project some years before. On the other side, if you create terrains often, T-Spline offer you more flexibility to create and modify the terrain. My suggestion is for you to create your own export scheme. You might want to still do this for splines, but not for arcs and circles. The T-Spline job isn’t a big part, maybe you can create the terrain with standard mesh tools and the weaverbird smoothing only. The curve tesseleation parameters tell Rhino how to break up arcs, circles and splines into short line segments for systems that can’t handle them. I feel good to create the terrain per drawing “mesh” lines, perfect to control, best for adding details where needed. I used the weaverbird smoothing because in the past there was a T-spline problem to keep edges unsmoothed (solved per T-Spline 4). My workflow was that I created a mesh of lines, converted the lines to a mesh object (per t-spline _tsFromLines), smoothing the mesh per catmullclark smoothing from weaverbird ( Weaverbird – Topological Mesh Editor | Giulio Piacentino). I used a planar projection from the top and mapped anything - grass, ways, sand … all in one material and visibility controlled by transparency maps at the different layers. Some years before I was working on a large terrain and I worked with a mesh. Smoothen surface without affecting the edges? Rhino for Windows ![]()
