Ok first thing first, both great contributions for humble 3d artists like me lacking programming skills.. although the existence of several conflicts between the two "mods".
First thing first: once I first added mystymood to my scripts, the shade-c depth of field stopped working. I figured out later that it was due to the following line of code in mystymood's sky_template.c "fog_color = 1;"
If I set that to zero or erase that line of code depth of field works again but I have of course no fog.
Also the mystymood's lensflare doesn't work when shade-c is on, why?
What I care about the most is about some sort of flickering edges on my meshes when I have shade-c ON, or more precise like if there was no antialiasing at all, despite the fact that I'm set "d3d_antialias = 9;"

1.Why can't I have fog ON along with shade-c's depth of field?
2.Why does my lensflare disappear when shade-c is ON?
-And the most important
3.Why does the antialiasing (I think it's antialiasing) doesn't work when shade-c is ON?
