What is the best way to cut a environment 3D model?

The best way to cut an environment 3D model relies on its complexity—use boolean operations for structured shapes or sculpting tools for organic forms, via 3D software matching your workflow. Boolean tools (like subtract/split) work for structured environments (e.g., buildings, walls), keeping edges clean for game levels or architectural renders. Sculpting (masking, dynamic topology) suits irregular terrain or natural elements, preserving organic details. For beginners, start with Blender’s free Boolean Modifier for simple cuts, then explore sculpting tools as you take on more complex models.
