Contains some stuff I made over time. You can use them freely on your maps:
Spheres: radius 2, 3, 4, and 5
3 donuts with different radii (4, 6 and 8 units), but the same thickness (4 units)
some arches
some cones (in the big building's roof, you can rearrange those into real cones)
some arches (the big building)
some 45 degree arches, to match those above
a dirt texture
some other crap you might find useful
if you find this stuff useful, i might post another batch later.
cheers!
