SP - Reorder Grid Index
MODIFIER TOOL
SP surfaces are dependent to a specific index order to work, so this tool reorders it in case you have a grid with incorrect vertices index.
Use cases
Apply it once after : * Separating two grids from the same mesh objects * Making a grid from a subdivided quad or any manually made grid
As a consequence this simplifies greatly the workflow, especially if you want to convert your mesh models to SurfacePsycho
