Agenda

1. How to make terrain with Mesh - Jessica Chung
2. If debug setting "RenderVolumeLODFactor" is not volatile (hence not just a builders' tool), does it mean there is no reference for LOD planning? [Bunnie Mills]
3. Some private estate owners have started implementing policies to prohibit the use of mesh on their land in order to keep the experience enjoyable for users of legacy viewers who see mesh items only as random polygons. While it is entirely within their rights to do so, it also creates a conflict with Linden Lab's Policy on Third-Party Viewers which states that the use of unsupported viewers must not be detrimental to anyone else's Second Life experience. Since most SL residents are not familiar with the technical details of mesh, it appears to be only a matter of time until people get banned for taking mesh attachments into regions where they are not allowed. Are there any plans to resolve this conflict, e.g. by stopping the server from sending mesh assets to viewers that cannot render them? [Masami Kuramoto]
4. Can someone here please explain to me why I just worked my ass off for 2 weeks on a project trying to keep it under 32 prims physically. Finally get it working tonight my physics weight is 31.9. PE is 363. I turn physics on and the physics weight jumps up to f***ing 915..?!? which puts the entire object to 916 PE.... what is the point of it listing as 31.9 physics when clearly for some reason its simply NOT? all of the mesh physics models combined are under 200 polygons. Really losing any hope of mesh what so ever (Moo Spyker)
5. There has been some confusion over which LL Convex Decomposition Stub Library TPV's & Open Source developers should be building from to build viewers either with or without a completed stub convex decomposition library. Currently there are at least two & possibly more including snowstorm development team libraries containing llconvexdecomposition libraries on the LL Bitbucket Repository. Can you please clarify to TPV & Open Source Viewer Developers which library is 1) most up to date, 2) the correct stub library to build from that will build successfully with or without a the stub library completed? [Jusden Jonstone]
6. Will Linked Rigged Mesh be supported? Currently theres a critical bug that causes a Update to a linked rigged mesh to revert all attached rigged mesh to the updated rigged mesh's upload default for a single game frame, per each llSetLinkPrimitiveParams event (CTS-759, The Bug in action can be seen in http://www.youtube.com/watch?v=X-fCaFXFevE , Thought I believe the case may have been directed to a internal JIRA, could I also have a confirmation on that?) [Matti Deigan]
7. After experimenting with rigged mesh in Blender 2.59 after the last mesh meeting, I found that a rigged mesh without joint offsets still works fine. But, a mesh with joint offsets still comes into SL mangled [Ashasekayi Ra]: http://community.secondlife.com/t5/Mesh/Joint-Offsets-in-Blender-2-59/td-p/1040777
8. Are we there yet? Are you rolling mesh out to the whole grid this week? [Vivienne Daguerre]
9. Please provide us with more information about upcoming ARC? Things like: default limits, ways of alerting users etc. Information in advance will help creators to plan their meshes better. [Maniac Choche]
10. Prim costs for large mesh objects seems a little strange. It makes sense for objects which are extremely complex (15k+ polys) due to drawing a lot of detail at longer ranges, but it seems less sensible when you take into account the rendering cost of classic prims. Is there any way that prim costs based on size can be much more strongly influenced by complexity so that large, lower poly builds are not significantly more expensive than smaller ones? And for that matter, is it possible that in the future we can specify ideal ranges at which each LoD can be viewed (influenced of course by the viewer's own settings), as well as linked build LoDs so all mesh pieces linked together show the appropriate matching LoDs? [Feynt Mistral]
11. where did you hide cts-670, cant find it in shining, too, so not moved there (was autoscaling in importer between lodlevels) and whats status on this[the bunny]
12. Would it still be possible to go back to displaying the 2D pacman shape for clients that cannot display mesh properly? Nowdays when mesh render as spehere, cut cube or hollow cylinder it is hard to tell if the build is just ugly or a mesh object.
13. Is Falcon still at the Lab? And if so, how is he doing? (arton Rotaru)
14. Pivot offset? [Drongle]
