(links anyone?)
The problem is the loadingscreen picture.
I think I’m missing the command to create those nice grey frames (just like in the original maps).
About levelshots and editing
There is no command for that. What you need to do is create the loading pic, give it an alpha-channel, and then see to it that the part around the pic will not be displayed due to making it black (i think) in the alpha-channel.
This is a link to a german tutorial I used with great success:

You probably need one of them too, but i m at work n can’t look it up for you right now. But i don’t think you ll get an alphachannel working without a shader too, so u ll be right.
Still, just the shader won’t do the work, you need a welldone tga-file including an alpha-channel and the “erased” edge of your pic too.
