Convert screenspace coordinates (top-left origin) to worldspace coordinates. Read before you react!

OK, I give up.

I’m trying to convert a screenspace coordinate to worldspace coordinate and I was able to perform some transformations using

Camera.ViewportToWorldPoint Camera.ScreenToWorldPoint

They transform, but incorrectly. Is there anything else I should consider before using these methods?

This guy seems to have the same problem too:

Thanks in advance.

They work as they should. Where do you use the world position? The other question you’ve linked has a different problem i guess. He’s using the GL class without setting a projection / modelview matrix so his coordinate system is something from the last rendered object.

Just read the docs on
