@ForestOwl, here is a workflow using Rhino and ZBrush for the outer shell of the above model. It doesn’t take into account the inner shell (that you’ve also provided), since both meshes, when joined and welded, don’t provide a solid, watertight mesh and are thus basically useless.
Unify the mesh normals of your mesh surface. This can be done in Rhino, as well as Grasshopper. By “mesh surface” I mean an open, non-watertight mesh.
Export the baked mesh surface as OBJ.
- In the Tool menu, click on Import and open your OBJ. Your mesh surface should now be your selected tool.
- Drag the tool on the canvas.
- Go to/activate Edit mode** (T).
- Make your mesh surface - now on the canvas - a PolyMesh (Tool>Make PolyMesh3D).
- Select the ZModeler brush (B+Z+M) from the brush menu. Now hover your mouse over a mesh face of your mesh surface, and hold Space. In the ZModeler menu select Extrude, All Polygons, and set the Step Size (i.e. 0.025). Now you can release Space and extrude your entire mesh by dragging a face.
- Got to the ZRemesher menu (Tool>Geometry>ZRemeshes). Activate FreezeBorder and KeepGroups. Set SmoothGroups to 0.0, and the Target Polygon Count to Same. Now click on ZRemesher.
- Export your tool/mesh as OBJ (Tool>Export).
- Back in Rhino, import your mesh and fire up Grasshopper.
- In Grasshopper, import your mesh, and if you exported Polygroups - which is done by this workflow -, you need to join and weld these first.
- Use the Catmull-Clark component from Weaverbird to smooth your mesh further.
You can skip step 7, the extrusion, if you export a watertight, solid mesh from Rhino to ZBrush. Remeshing is always a good idea though, since it provides you a neat, regular quad mesh that can be cleanly subdivided further.
You may notice that there’s not much DynaMesh-ing going on here, simply because I got better results without it. You may have to reintroduce it though, if your meshes get messier or more complex.
My bad, I must have misinterpreted one of your previous posts! I didn’t have much luck with DynaMesh and the Project option though, even when using a solid mesh. Maybe you could expand a little upon this technique?
