Triangulate square mesh randomly I am using blender to triangulate a mesh that I want to use for a physics simulation (outside blender). For that, I want to randomly remesh it. The triangulate modifier is not enough, as there is a preferent edge direction, which I want to avoid.

Ideally, adding random vertices inside the quad and force a remeshing algorithm to use this points would work, but I have no idea how to do it or if it is even possible in blender.
Create a new shapekey for your plane.  Enter edit mode on that shapekey.

Use transform-&gt;randomize operation.

Use a triangulate faces operation.  In operator panel, specify &quot;shortest diagonal.&quot;

Leave edit mode and delete your shapekey.
