2D Collider in a triangle

[sirio21]

Hi, i’d imported a simple triangle from 3d studio. How can i setup a collider that fit the shape?
A 2d polygon create a 5 vertices shape (why cant be changed to 3)?

You can add and delete vertices from the collider as needed. Unity - Manual: Polygon Collider 2D reference

ou can edit the polygon’s shape directly by holding down the shift key as you move the mouse over an edge or vertex in the Scene view. You can move an existing vertex by shift-dragging when the mouse is over that vertex. If you shift-drag while the mouse is over an edge then a new vertex will be created at the mouse location. You can remove a vertex by holding down the ctrl/cmd key while clicking on it.

Thanks for the link!
