im no dx coder, but it looks rather convincing

The problem is not with a single model, but rather when you have several models one behind another...

the transparent green hide"s only the polys from the same subobject ( say you have a turret behind a grider, the turret will show dfine, so will a fighter flying behind it ).

like was said in OpenGL most zbuffer problems origionate from faulty calls to gluPerspective a good example of some of my code is this

Code: [Select]


    gluPerspective( 85.0f, float(Get2DResX())/float(Get2DResY()), 0.001f, 10000000.0f );


but it also has to do with your video card - i've got this cranked really close for the ZClip because my video card can handle it, but a publish build will have 0.1 - even the GeForce FX has huge clipping problems with that call of mine, when my Radeon 7500 does not - but 0.0001 it gets clippy, at 0.00001 it freaks

The difference between a near Z of 0.01 and 0.001 is huge. I'm betting you can even get away with a near Z of about 1, without visible differences, and it'll help a lot.
