Here is a beta of my training course map. It has a paintball sort of feel to it but with lots of twists and turns. Please try and comment.

Cool project.
You have no shaders, all of them are missing.
It's also some lamptextures that are missing, and the water texture.
The windows by terror spawn looks a bit weird. But the rest looks ok.

yea í kinda like the theme of your map milky, not bad for a first!. But as nitram also mention, there is some critical problems.

Heres a quick checklist for ya:

Fix the shader issue (so all textures behave properly and make the right sound)

Add the missing water texture to your pk3.

Line up some of your brushes right. (so there is no gap between them)

Remove all windows, as i doubt they will work. (cant see enemy through them)

Some of your texture dont fit right (like the lamps in the above tunnels and so)

Also try to have another look at your lightning in general.


Keep mapping!

I don't know how to make the shaders make the right noise when you step on them... can anyone help?

Its hard to say exactly what the problem is without any information.
But most likely you have not set up Radiant project settings right or you simply have the wrong shaderlist.txt

Milkydeathgrind, could you paste here the exact content of your custinfoparms.txt. The file is located in scripts folder.
