Geometry Subdivide

Geometry Subdivide splits every triangle into four — shared edges split once, so the surface stays sealed — up to three times. Smooth then relaxes each vertex toward the average of its neighbours; at 1 a box becomes nearly a pebble.

The point of it is not prettier triangles. It is that low-poly shapes gain the vertices that Geometry Noise and Geometry Deform need to bite into. A deform on a 12-triangle box does nothing; on the same box subdivided twice it does everything.

Capped at 400 000 triangles.

• Prepare for displacement — The standard first step before Noise or Deform.
• Smooth a primitive — Smooth at 1 rounds a box into an organic blob.
• Better silhouettes — A low-resolution import gains a smoother outline.
• Denser sampling — More vertices means finer point clouds from Geometry to Points.
• Cloth and terrain bases — A plane subdivided is the starting point for both.

• Each iteration multiplies triangles by four. Two is usually plenty; three is rarely necessary.
• Raising the source shape's own Resolution is cheaper than subdividing it afterwards, when that option exists.
• Smooth shrinks the shape slightly — that is what relaxation does; scale back up if it matters.
• Subdivide, then Noise, then look at the counts before adding anything else to the chain.
