Zbuffers and multiple passes

Recommended Posts

Leave it enabled and use D3DCMP_LESSEQUAL or D3DCMP_EQUAL for your Z comparison.

Pass 1 writes to the Z buffer

Pass 2 tests the Z buffer, and if the Z of the new pixels is equal to the Z of the existing pixels (it will be since you''re passing the *same* polygons) then the 2nd pass gets written.
