SabreCSG – a set of level design tools for Unity

SabreCSG is a free set of level design tools for constructing levels inside the Unity game engine. Constructive Solid Geometry techniques used in SabreCSG allow you to add and subtract brushes to create complex levels without traditional 3D software.

The toolkit is now open sourced under the MIT License. You can follow SabreCSG on on this Github repository.

Features

• Boolean CSG algorithm supporting partial rebuilding

• Draw tools to rapidly create levels by drawing brushes directly
• Resize tools allow you to resize spaces intuitively

• Vertex tools to refine and add precision details
• Change materials or edit UVs with surface tools built for level design

• Clip planes allow you to bevel brushes or even split them in two
• Export built geometry to .OBJ for use in external 3D tools

• Vertex Colors – Apply vertex colors per face which are baked into the built meshes
• Experimental Code API – Experimental support for procedurally generating levels through code

You can find documentation and videos on how to use SabreCSG on the official website.
