marcosbitetti / grid-slicer.py
Last active August 2, 2025 18:41
This tool get a large terrain on Blender, and create thin objects from it. Slicing original object. Useful to make game levels, spliting a huge scene and optimize each slice for LOD
import bpy
import bmesh
from mathutils import Vector
def slice_object_by_grid(obj_name, cell_size_x=5.0, cell_size_y=5.0):
"""
Slices a mesh object into new objects based on a grid.
Considers faces if *any* of their vertices fall within the grid cell.
