0006797: [BULLETSIM] Mesh object issues - asset would not mesh
I have isolated one meshing issue on a collada mesh object to a single "pipe" piece... The item can be rezzed in world and looks visually okay. See attached image "2013-10-11-Mesh-Pipe-for-BulletSim-Error.jpg"

I attach the item as an IAR file "BulletSim-Tests-Mesh-Pipe.iar".

But if this is loaded into a region with BulletSim physics, the console reports..

09:54:51 - [HGScene]: RezObject itemID=de7bfb8b-e9a3-4862-a26f-991e3d1c7eb3 from

1. Load the IAR BulletSim-Tests-Mesh-Pipe.iar

2. Rez the "pipe" items in the contents to a region with BulletSim physics enabled.

3. Observe the items looks visually fine, but also observe the BulletSim errord.
Detailed OpenSim.log entry....

I see these same message on startup on many sims in the log and on console.
