Why not linearize it then? I assume the different fading based on near/far plane etc. is not intended.

Seemed like more effort than it's worth since I would have to plumb through the near/far values (which can apparently be different for every view) with a uniform. There's an r_zNear GLSL define, but it seems to have a tenuous (at best) connection with the value which is actually used.

Yeah, zFar is supposed to cover the whole map in whatever direction, while zNear can change for portals. depthtile1_vp does this, albeit with r_zNear, but if it's discreet enough then it's fine as is I guess.

Retargeted this to 0.55 to avoid future merge conflicts. |
Divide out the w coordinate in the vertex shader instead of the fragment shader. Also add comment about hacky depth fraction calc.
