Mesh Uploads
This mesh upload process is used for all reference uploads of Ruth2 and Roth2 in order to maintain a consistency across grids.
Firestorm 6 has a new mesh uploader by Beq Janus that is a great improvement (so much that LL is porting it back into their viewer) that we use for all uploads. The SL-specific build of Firestorm should be used for SL uploads as it uses the Havoc physics engine (licensed only for SL use) while the “OpenSimlulator” build must be used for all other grids.
There is a nice overview of the Mesh Upload process in this OpenSimulator wiki post.
Another useful discussion of mesh uploads is Oz Wayfarer's post to the Kitely Building and Texturing forum. Specifically section 4 details the differences between SL and OpenSim regarding physics. The additional detail of rigged vs non-rigged mesh is not addressed but suffice it to say the OS case seems compelling enough to require a simple physics model for our OpenSim uploads, rigged or not.
Upload Model
The process for uploading rigged mesh (avatars) starts in the Build → Uploads → Mesh Model menu in Firestorm:
- Model Name: use DAE filename
- This model represents…”: If this is present next to the model name then you have an older viewer as it has been removed in recent Firestorm releases. It apparently was never used by the back-end and can be left unset on viewers that have it.
- Level of Detail tab
- Medium/Low/Lowest: Due to how SL calculates LoD on rigged attachments the Low and Lowest settings are rarely if ever rendered by the viewer. We set them intentionally small to keep the reported complexity low. See the tables for each specific body for the actual values used. This SL forum thread has a recent-ish discussion around what is happening. LOD suggestions and recommendations at https://serie-ous.style/ss/ruth/mesh/roth
- Generate Normals: do not check this box
- Physics tab
- Step 1: Use file PhysicsTriPlane.dae (From the RuthAndRoth/Reference repo) for the physics model
- Step 2 and 3: Do NOT use the Analyze and Simplify buttons for rigged mesh (citation?)
- Upload Options tab
- Scale: leave scale at the default value 1.000
- Include textures: do not check this box
- Include skin weight: check this box
- Include joint positions: do not check this box (citation?)
Reference Box
After uploading:
- Set all mesh uploads to full permissions (leave no-transfer for pre-release mesh only)
- Attach to an appropriate place to set the default attach point:
- body (full, body and and headless (body+hands+feet): avatar center
- head: chin (leave skull for attached hair)
- hands: left upper arm
- feet: left lower leg
- eyes: left eyeball
