Um, what's the undesired effect?
Please look at those 2 links. First the before than the Effect.
EDIT: If you cant tell the effect is the grid and the side bar turns black after i load the MD2.

Uhm, your code probably either moves the camera away from your original stuff, or overwrites it since the loading code is after the other code.
Author
its not overwriting things because i moved the loadeing code around and it was the same. Its not moving the camera because ive tried rendering it before the camera.

Maybe it''s that a big monster comes and takes over his desktop!
That''s what I would have though
...Being serious though, it looks like you''re setting up your projections wrong. Try it like this:
glMatrixMode(GL_PROJECTION);glPushMatrix();glLoadIdentity();//--Width then heightglOrtho(0, SCREEN_WIDTH, 0, SCREEN_HEIGHT, -1, 1);//--Might also be://glOrtho(0, SCREEN_WIDTH, 0, SCREEN_HEIGHT, 0, 1);//--Or... (I usually have to play with the orthographic //--projection for it to work right...)//glOrtho(0, SCREEN_WIDTH, SCREEN_HEIGHT, 0, 0, 1);glMatrixMode(GL_MODELVIEW);glLoadIdentity();////--Render 2D Data//glMatrixMode(GL_PROJECTION);glPopMatrix();glMatrixMode(GL_MODELVIEW);////--Render 3D Data//Also, I would render the 3D grid then the model. If not you''re going to have render order problems (The grid will look like it''s going through the model)
Also, whats g_bar();? Is that the frame on the left side? If it is, why are you rendering it in the perspective projection area instead of the orthographic projection?
Also, when rendering your quake model, does it reverse the winding order of the vertices? If it does and you have glCullFace(GL_FRONT);, then it could be culling the 2D data?
Also, did you try taking out glDepthFunc(GL_LEQUAL); as that might be doing it? Just comment it out once and see what it does...
Theres a lot of things that it could be. It''s hard to fix it without actually playing with it.

commenting out glDepthFunc(GL_LEQUAL); doesnt help and g_bar(); is the calcuations for how much hp/mp is left in the health/mp bar.
Well here is what I was mostly concerned about:
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glColor3f(1,1,1);
glMatrixMode(GL_PROJECTION);
glOrtho(0,SCREEN_HEIGHT,0,SCREEN_WIDTH,500,-500);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glPopMatrix();
glPushMatrix();
If I''m thinking right, your popping the modelview matrix. Usually when you don''t want the matrices messed with, you push a new matrix, do whatever you have to do, and then pop it. I''ve never seen it where you pop a matrix after setting the modelview. Take out the pushing and popping and see what happens...

glMatrixMode(GL_MODELVIEW);

glPopMatrix();
