how do I update it myself??
i don't have a clue what that undefined (possibly removed from 1.4.2) function does...
anyway I made a shader that puts the depth in fourth component, but the problem is that i loaded a Quake3 map and i can't get it to display the light maps...
which texture layer is that???

well if someone would explain to me what to do about these w functions I would be able to make A depth pass that is able to put 16 bits of precision into the alpha channel (FPT = wonders)

well i cannot put the depth in the fourth component because it changes alpha and then things blend together

I NEED ANSWEARS CMON PPL!
I need 16 bit precision that is only achievable with MRT or FPT.

You can pack 32 data to to R8G8B8A8. Check my Deferred Shading demo for that.

but i need the RGB channels so unless I have Floating point Texture i am not able to pack 16 or 32 bits of prec into alpha channel

You need 32 bits depth, right? So, You can write it to R32F etc. or pack it to R8G8B8A8 and unpack it in next shader.

right R32F, but your patch does not work!

well I still REALLY need MRTs for DoF cause otherwise I cannot use the transparent render state.
