Booleans Improvements

Booleans

The boolean algorithm has been updated to align with 3ds Max. This enables a shared, unified core boolean engine between Maya and 3ds Max. With this update, the predictability and reliability of booleans has improved.

Complex Geometry

In previous Maya booleans, operations could fail. Boolean operations performed well with many simpler examples but could easily fail with more complex geometry. In the following example with numerous spheres, previously the operation would fail, be adjusted and then fail in new areas. In this update, it works and the resultant geometry is as expected.

Coincident Vertices

When vertices are perfectly on top of one another, booleans could previously fail due to misunderstanding this type of geometry. In the following example, the sphere and torus have vertices perfectly aligned. This operation would not succeed in past versions and now performs seamlessly.

Booleans could also cause issues downstream previously when it produced ouput meshes that incorrectly created coincident vertices. This update resolves coincident vertices and avoids generating them, as seen in the following example.

Coplanar Geometry

In previous versions, the boolean operation could produce unexpected results with coplanar geometry. Now, the operation resolves any overlapping surface discrepancies that impact the result.
