Alright, since there's a lack of good maps, or use of good techniques, I'm making this thread to teach you guys some cool things about mapping.
Torque ConstructorPortalsThese won't teleport you, so don't get excited.Portals are brushes that are meant for doors and such, so when you look outside you don't need to see extra geometry to prevent lag, much like Blockland's brick system hiding brick faces that are completely covered.
How to:
Create a brush where you want the portal, fit the brush into the spot. Now select it, and in the properties box, check portal, as shown below. The brush will turn pink.

Note:
Make sure the room is closed, make sure there are no spots that you can see out of other than where you have a portal.
Pie ToolThe pie tool is a new tool in the latest version of Torque Constructor. It's used to make tubes, banked turns, and some more. It's found under the user section of the tools box. Feel free to paly with the settings, here's what some of them do:
Segments - How many sections are in the pie.
Start - The first section of the pie, default 0.
End - The last section of the pie.
Hollow Center - Makes a tube if checked.
Center Size X - How many units the center's size will be on the X axis.
Center Size Y - How many units the center's size will be on the Y axis.
Center Top Adjust - How many units high the center is.
Center Bottom Adjust - How many units high the bottom is.
Outside Slope - How high the pie gets, as in swirling up.
Inside Slope - I don't know right now.
That's all for now, I'm just too damn lazy to do the rest right now, I'll do it soon.
