I have 2 different shaders, and when I change the shader (glUseProgram), it seems that the depth information is lost, because everything drawn with the 2nd shader appears completely on top of anything drawn by the first shader.

If I switch the order of shader use/drawing, then it's the same (the last drawn object always appears on top of the first drawn object if there is a shader change between the 2 objects, even if the last drawn object is further away)

In Direct3D, multipass shaders are simple to use because you can literally define passes within a program. In OpenGL, it seems a bit more complex because it is possible to give a shader program as many vertex, geometry, and fragment shaders as you want. A popular example of a multipass shader is… >>> More
