Buildings in Torque?

#1 What kind of building? Buildings range from very easy to build to very hard.
A simple 4 wall and flat roof building could be done with the sketch tool, for everything more complex you would need to use a modeling program.

#2 Look at tutorials for Google's Sketchup it is properly one of the easiest modelling tools.

You then export it as .dae (collada) format.

Sketchup is good because its free and has lots of tutorials out there for it and also easy to use, any modelling program will do. If you want to be a 3D artist then you want to learn 3DSMAX and/or MAYA (expensive industry standard) or Blender (Free and does everything) those all have steep learning curves but that is what you use to create great art.

#3 Sketchup may seem to be easier at the beginning, but in the long term you will be happier with a more complicated program, because you have more functions there.

#4 I second Edward's suggestion of using SketchUp to build your buildings.
Another program to use is something called Blender. The UI is a little difficult to master, but there is a website www.BlenderCookie.org that has plenty of video tutorials to guide you.

#5 I personally would recommend that you artist up and learn Blender. Go to the website that Gary suggested and learn how to make what you need and import it into Torque because there is a lot to learn. Additionally, you will want to soon do more than just make buildings.

#6 A building is already one of the hardest things you can do...

#7 Buildings are easy, good character limb deformation is hard ...

#8 Yes most just make a block with window textures on it for a building, that is easy, but I mean a real building with full modeled out interiors with proper texturing.

#9 Rather a building than C'thulu....

#10 A video game is as detailed or un-detailed as required. Remember whatever you create is fake no matter how real you think you are modeling the object. So remember it is okay to use smoke and mirrors to get the effect you want. If you want a remote cityscape then pre-render that if you can. It will make the world look more alive with less polygons.

So if you want to make a building you can't enter then a block with textures might be enough. If you need to interact it may need more. A really good example of this concept is the Sector T3D demo (www.garagegames.com/). This has close up buildings and pre-rendered buildings in the distance. Definitely a good one to check out for ideas.
