Upload Settings for OpenSim
The following are upload settings used for our OpenSim release. Although there are many opinions on how to correctly upload a rigged Collada mesh file, the settings used for our release was chosen to provide the lowest Avatar Rendering Complexity possible while maintaining the integrity and quality of the mesh asset.
- Viewer: Firestorm-Releasex64 5.0.11.53634
- OpenSim: 0.9.1.0 Dev
- Physics Engine: Bulletsim
- Database: mariaDB | FS Asset | Debian | mono 3.2
The Collada upload file is made up of 8 upper-body parts plus 18 lower-body parts and uploaded as a linkset.
- High - Triangles: 11444 Vertices: 8442
- Medium - Triangles: 5563 Vertices: 4960
- Low¹ - Triangles: 201 Vertices: 275
- Lowest¹ - Triangles: 201 Vertices: 273
High LODS comes from the *.dae file's actual triangle & vertices counts. Medium to Lowest LODS are generated based on an error threshold or a triangle limit value either assigned by the viewer or manually entered by the user.
¹ Custom LOD settings for avatar attachment often referred to as the LOD Trick. By using zero(0) Triangle Limit for the Low and the Lowest LOD, a minimum triangle & vertices counts are assigned to the mesh asset and since the viewer ignores the Low and the Lowest LOD for avatar attachments, a much lower Avatar Rendering Complexity is achieved.
In OpenSim, ubODE physics engine requires that you select a physics level of detail(Step 1 - physics tab) for your mesh. Since Avatar attachments do not use collision shapes, you can select a low setting here. I selected the Physics LOD Low.
IMPORTANT: Do not use or click the Analyze button (Step 2) when uploading to OpenSim.
IMPORTANT: When uploading a linkset to OpenSim, do not use a cube for collision shape.
