Triangulate Modifier

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

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 along their shortest diagonal.
Longest Diagonal: Split the quads along their longest diagonal. This is the preferred mode for cloth simulations.

N-gon Method

Beauty: Arrange the new triangles nicely, slower method.
Clip: Splits n-gons using an ear-clipping algorithm (the same method of tessellation used for viewport display).

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.

Keep Normals

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