Chisel (WIP)

Chisel is an extension for Unity that allows for rapid, iterative, non destructive level editing!

Example

Note:

Chisel requires Unity 6 or newer
UX is still under development
CSG algorithm is still under development
It is not yet ready for production, but please feel free to try it out, or better yet, help out!

Features (incomplete)

Constructive Solid Geometry Algorithm that generates geometry in real-time
Add and remove geometry to your level using CSG allows for fluid, interactive, non destructive workflows
Higher level "generators" that create more complicated geometry to perform CSG with, while retaining context of what it is you're creating (if you create stairs, these will remain stairs that you can edit and tweak)
Hierarchical Constructive Solid Geometry, allows for generators and brushes to be act as if they're one whole (composite), to perform CSG on other objects with
Works well with prefabs, drag and drop windows onto walls including their holes
Draw 2D shapes (possible to turn straight lines into curves) on existing CSG surfaces and extrude them
Precise snapping to surfaces, edges, vertices and grid lines
Rotatable & movable grid

Planned Features (incomplete, and in random order):

Extensions:

If you find any failure cases, if possible please provide us with a reproducible scene so we can more easily fix it!

The core technology is based on the algorithm explained in this GDC 2020 talk
