Description of the problem

i'm trying to subdivide a plane geometry on threeJS using SubdivisionModifie, i did this the last year and it worked fine, but now i updated my threeJS and SubdivisionModifie, and when i try to subdivide my plane geometry give me a different result.

code:

var subdivisions = 4; var modifier = new THREE.SubdivisionModifier( subdivisions ); modifier.modify( geometry, subdivisions ); geometry.computeFaceNormals(); geometry.computeVertexNormals(); child.geometry.dispose(); child.geometry = geometry;

@JordiGoPython do you remember what version you used last year? I'm guessing it could be using the Catmull-Clark that works with quads in SubdivisionModifier
