Hi everyone, my level design tools for Unity are a 33% off for the next 22 hours
SabreCSG allows you to build levels in-engine by using additive and subtractive brushes allowing you to very rapidly and non-destructively build and iterate levels. By using brushes and CSG you're able to make both small and huge changes very rapidly as the build engine takes care of mesh generation, which avoids destructive coupling of level design with mesh tools.
Please let me know if you have any questions or feedback
