Bumpers: Missing underside polygons on cap.

[Pandelii]

The bumpers are currently missing the bottom facing polys on the cap. This produces some artifacts on highly reflective tables. The materials could be made to be double sided to correct for this, but it would be cheaper and more correct to generate the appropriate faces.

Bumper meshes are hard-coded. If you have a chance to export them, fix the polys and post the resulting mesh here so I can update the code that'd be awesome.

Will do. Any specific format?

.obj is fine.
