How to convert world position of a pixel to a depth value? (shader)
My shader use a distance texture to calculate the world position of pixels. So far, i can make it get the correct world position, and make it correctly interact with the unity lighting system (even point light). and now i want to correctly interact with the depth so that i can do depth test, projecting or even shadow rendering. But i can't calculate the correct depth value.
Do you know how to convert world position of a pixel to a depth value?
I think that would be the Z value of your screen-space point. (that's the one you get when use use the UNITY_$$anonymous$$ATRIX_$$anonymous$$VP matrix.) Not sure about this though...grain of salt.
