You didn't texture it. concrete.jpg and null.jpg are the default textures for new torque maps.
Install this pack:
http://downloads.sourceforge.net/quark/Torque_textures.zipThat will let you use all the default torque textures in quark. Maybe later I'll get all the default Blockland textures and make a quark plugin out of them.
Then follow this tutorial to texture:
http://quark.sourceforge.net/infobase/maped.tutorial.polyhedrons.html#texturingWhen you go to pick textures, you should see a tree view (a bit like windows explorer) to the left that lists all the textures you have. There will be two categories, Searched and Torque Textures. Under Torque Textures you'll see Lees, Book, common and general. Pick a texture out of there.
To compile your map, go to Torque>Export220Map/Build High Detail Map
It will export your map and your textures.
If you need to find out how to do something quick, the quark infobase is the best place to look:
http://quark.sourceforge.net/infobase/index.htmlIt's even got the definition of a brush:
Most basicly its a solid cube which is convex. A polyhedron consists of at least 4 faces so they create a 3-sided pyramid, and up to several hundred faces which probably will be something like a sphere. Synonyms that are commonly used for polyhedrons are; brush, cube.
But if you can't find something or don't know where to look, feel free to ask, I don't really mind answering questions about interiors and mapping. I just get annoyed when people still need help editing a shortcut to start the mission editor even after watching a 4 minute video on how to right click and type 2 words. I'm just about ready to charge people a dollar for me to open up remote desktop and do it for them.
