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.

Método para converter quadriláteros

Divide os quadriláteros em triângulos bonitos, método mais lento.


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

Alternativo fixo

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

Diagonal mais curta

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

Polygon Method

Arrange the new triangles nicely, slower method.


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

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.
