Assault Cube mapping contest goes green

[SiL3nT]

I'm sorry but I didn't get the custom media bit:

Correct me please:

.: I can make my own textures, but they have to be inside a clip (not in gameplay)

.: I cannot make a mapmodel as it would affect the gameplay because everyone doesn't have it. If so, I could let people download the textures/mapmodels. How do I do then?

Thanks in advance
