Spline tool with randomized asset placement. Editor slow to update because each adjustment to spline changes the asset randomization.
Meshes supported with edge loops for spline deformation
Spline tool does the placement heavy lifting for tunnels. The tunnels were merged down and marked for nanite during run-time.
Detail rough and normal for ground tile
