I need some assistance with Blender’s To Sphere option. I’ve created a mountainous terrain with a 32x32 grid, and I want a leaning tower emerging from the ground. I tried to delete a square portion of the grid, then set the hole To Sphere, so that I might extrude a hollow tower from the mesh.
The only problem is that the To Sphere option will only scale bigger than the hole, not smaller to fit within the original square hole.
You might have an easier time creating the tower out of a cylinder, positioning it the way you want it, then connecting it with the terrain using ‘make faces’ between the bottom row of verts in the cylinder and the verts surrounding the hole in the grid. Just make sure the cylinder and the hole have the same number of vertices.
