Display enemies behind walls - WH?

Hi,

you record the same clip two times with different settings.
The difference will be that you record one normal clip and one with greenscreening or bluescreening. Taken from cvarlist.txt in the mme folder:

mme_skyKey [0-9, a-z]
Fills the skybox with a solid color.
Use it in combination with r_drawWorld disabled to create greenscreen, bluescreen and so on.
That one is important. Combine it with r_drawworld "0" and you get a complete keying screen I reckon.

mme_worldShader [shadername]
This command will replace all the shaders making up the level into this one. Try console, mme/blue, mme/green or something for interesting results.
I haven't used that one. Might be helpful so you can play around with that.

And later one when you have captured both clips, you key out the background color like green or blue and then you have only the models showing up through all walls. This is how most people do it. Then there is one cvar that helps you to only show the players instead of everything including ammo and weapons. It's somewhere in the cvarlist as well but I am too lazy now.
Good luck!
