This command will take a mesh and reduce it into an approximation of the shape using boxes, ideal for collision detection where the goal is to reduce polygon count of the collision geometry.

REDUCE MESH Mesh Number, Block Mode, Near Mode, GX, GY, GZ

Mesh Number

Integer
The mesh to perform the reduction on

Block Mode

Integer
Reserved

Near Mode

Integer
Reserved

GX

Integer
Number of divisions along the X axis to create the reduced mesh

GY

Integer
Number of divisions along the Y axis to create the reduced mesh

GZ

Integer
Number of divisions along the Z axis to create the reduced mesh

This command does not return a value.
