Planar UV mapping

Hi all,

Say I have an imaginary square plane that I want to planar map.
The size could be anything but lets say 10x10 units.

What if I only got a piece of the corner of this plane but still want to map it as if it was 10x10 units? Can this be done in Unity?

I have the assumed size of the plane and I have at least one of the four corners. So the planar UV coordinates just needs to snap to the imaginary corners with the remaining corner as origin.

Thanks,

Jacob

I made this nice illustration to get a better understanding of what I’m trying to achieve.

So I have to map the mesh as if it was 2048 x 2048 and snapping to whichever of the four corners I’m left with.
In this case the lower left one.
