Triangulate Modifier

The Triangulate modifier converts all faces in a mesh (quads and polygons) to triangular faces. It fulfills the exact same function as the Triangulate tool in Edit Mode.

The Triangulate modifier.

Quad Method
Beauty

Split the quads in nice triangles, slower method.

Fixed

Split the quads on their 1st and 3rd vertices.

Fixed Alternate

Split the quads on their 2nd and 4th vertices.

Shortest Diagonal

Split the quads based on the diagonal distance between their vertices.

N-gon Method
Beauty

Arrange the new triangles nicely, slower method.

Clip

Split the polygons using an ear-clipping algorithm (gives similar results to the tessellation used for the viewport rendering).

Keep Normals

When using custom normals, try to preserve the same shading as before triangulation.

Minimum Vertices

Minimum number of vertices a face must have to be triangulated. For example, setting this value to 5, will prevent triangulation of quads and only triangulate N-gons.
