2D Polygon Collider

Is there a way to manually input the vertex positions on polygon colliders? I need precision, and I’m not getting it with just dragging the vertices.

I have sprites set up like in the image and made the collider for just the top part of the 2d Cube. But zoomed in, you can easily see the imprecision. If I can’t manually input vertex coords, how can I go about doing this properly?

You can use:

to set the points manually.

Just write a script and set it to ExecuteInEditMode or write a Editor Script itself.
