How to render Z-Depth

Our team wrote a SSAO shader that uses only the Z-depth of a scene and returns a black and white texture to be multiplied in screen. Ok, but we are having difficulties to render a good z-depth(with a descent gradient) and with models(not only the map geometry).

Does anyone knows an easy way to perform z-depth render with the dynamic models?

Take a look at the depthfx code. Although once you get into using floating point texture formats and such, it can become somewhat of a minefield of stupid/nasty driver bugs.

eihrul,

To become a "minefield of video driver bugs" is not a problem, cause we pretend to make the game primary compatible with only one card model.

so to fix the depth gradient i should set the texture to floating point format?

how can i render the depthmap with the dynamic models(players, objects) into it?

thanks

This is one of those situations where for me to explain it all would be as complicated as me going and implementing it myself.
