The main purpose of the tesselation is to have a some vertices density in the mesh to be able to do "puppet" deformations with some rigging (similar to the puppet tool of After Effects). They are usually only seen in 3D modeling tools as they mainly serve as a way to quickly fill in gaps in a mesh. You can do this per mesh by using the triangulate command (Ctrl T) in mesh edit mode. This is an object mode tool and we can add it to . For any mesh in object mode. The Triangulate modifier converts all faces in a mesh (quads and n-gons) to triangular faces. You can sometimes get away with switching to edit mode, selecting everything, and running the Triangulate operation. Inputs Mesh Standard geometry input.
