- Cylinder (for pipes, columns)
- Curved Cylinders (pipe corners)
- Sphere (for planets/moons)
- The UT pipe has a fat rim at one end like a Super Mario Bros pipe. It doesn't look good if you want a long pipe section.
- The UT pipe curve is okay, but it would be better to have a couple different radii versions (tight bend, medium bend, large bend)
- The UT moon badly distorts textures at the poles. It would be great to have a sphere mesh that can use equirectangular textures (like the ones here) without distortion
(An ideal scenario would be a repository of non-stock mesh packages that mappers can use. Either on one of the existing UT content sites, or I could probably set up a myself if enough people are willing to contribute mesh packages.)
