Will someone tutor me and help me make an underground map in a giant sphere? I've tried myself but it just turns out like garbage. Please no posts on this thread explaining. I need an actual demonstration. Like with team viewer or something. Thanks guys, -Bobby

I know that I should not reply, but I wan't to say something, go to play single player, load up the underground chapter, play it through, fly around in the level(to see overview) and take alot of screenshots from each place. It helps ALOT. I'm doing same way if some theme is new for me.

Edit: 69th post, lol.

Sp_a3_speed_ramp is included as an example map in the Portal 2 authoring tools. Refer to that map.

There is actually 4 maps available in the tools to look at or convert if ya want.Others are Multi player
