# In the latest release and beta viewers (244864 and 245931) the mesh uploader requires BOTH that the number of materials in each LOD has to be the same AND that the names of the materials (the material attributes of <triangles> or <polys> tags) of lower LODs must be a subset of those of the high LOD. This is equivalent to simply requiring that the set of materials must be identical for all LODs. In that context, the error message (issued only in the beta viewer) that mentions subsets is not meaningful, and the error message in both about number of materials is inadequate. This suggests that the reversion (from an earlier beta) to reqiring the same number of materials may be a mistake. Please indicate if that is so or if the reversion was deliberate. [Drongle McMahon] (to Drongle and for Linden's consideration: please consider the material fix Runitai did back in July. Perhaps this is the supposed "reversion"? If it is so, then it should not be broken again. There are Maya users out there. Angel Alphaville).
# I do have specific questions -- a LOT of them -- and will no doubt continue to have them. I like to find whatever answers are already out there, before I come begging in the forum. I haven't found a good up to date central location for troubleshooting. Information is strewn all over. The answers to my questions are probably there somewhere, but I can't find them. Forum members may be able to answer many questions, but what is LL's role in supporting mesh? There is quite a lot of SL-specific information that one must know to upload anything with a decent PE, yet that information is not made easily available and accessible, or apparently kept updated. What plans does LL /the mesh team have for providing support for mesh problems? (Pamela Galli)
# The mesh uploader in the new beta has a bug in the "materials checkbox" and keeps showing the models in plain white, as opposed to showing them coloured when materials each had a different default colour. It also is in a bizarre way affected by the windlight settings that may be set at the moment. All this had appeared in the Shining branch of code and we gave the heads up for this at a meeting a month ago. The model is eventually imported right, but with plain white it is not easy to see the shading when we generate the normals and play with the values. Note that this is on an Nvidia GTX460, Win7-64 based system. [Angel Alphaville]
#I'm not able to browse for custom physic models anymore, no matter which viewer version I use. i tried different computers (iMac, MBP), different OS (Lion, windows 7 on boot camp), different networks (at my home in switzerland, and one in germany), wifi and ethernet. When I select "select from file" (or however it's called, I'm on a german version), it won't even let me browse for a file, the button stays greyed out. I already uploaded many models successfully with custom physics, now it won't even work for those. I already filed a JIRA (SH-2684), but it disappeared and I never heard again about it, last message was from Dan at 11/15, he asked me for a model, which i sent to him. He sent me the link to viewer version 245867, which was compiled for windows and linux, only, but that didn't work for me (on bootcamp, of course). I'd wish I could go on working with mesh...

#Simball and Mesh - I am an avid Simball player. Simball is a Second Life sport that can be described as a kind of Hockey on hover boards, created by Sean Martin under the Trademark Vetox. It has gained some popularity, and a lot of popularity with the Japanese who have a league of their own. How will the new simulators that mesh introduces affect this game? Can Simball benefit from Mesh ramps that the board doesn't snag on in laggy conditions, like they sometimes do on the prim ramps? [Davido Chrome]
#Deformers: Since joint offsets/bone lengths aren't going to be supported by the mesh uploader at release, and since the latest mesh viewers do not support uploading BVH files where the hip is not the root joint, does this mean there will be a window of time where no new deformers are able to be created? (And did you mean to do that?) (Bloodsong Termagant)
#Deformers, Multiple: If an avatar wears more than one rigged mesh with joint offsets/bone lengths (when we get those ::nudgenudge::), which offsets/lengths will the avatar inherit? The ones from the first worn rig? The ones from the last worn rig? The ones from all partial rigs that don't overlap (ie: arm lengths from a sweater, shin lengths from a boot)? (Bloodsong Termagant)
#Slight Scaling bug with rigged items: I first rig an item in maya to the default skeleton, scaled specifically to the default male mesh avatar, then export/import the DAE. I then wear the default shape in SL, and wear the imported mesh item; Ideally, it should be identical in proportion and position to the initial rigged model since both are based on the default, as the data is based on the parent node of the skeleton. However, when imported, each time i notice a significant difference in scale - much narrower but also slightly taller and deeper front to back. I have noticed this repeatedly, with full avatars, with pants, with shirts and jackets and with a belt. Having no idea how this is occuring, I cannot come up with a method to counter the effect. Are you aware of this and can you help me solve the issue? Just scaling the bone lengths will not solve the problem, but only scales the problem.(Maxwell Graf)
#Can you confirm pricing for uploads information for the full release? I have heard conflicting reports from several Lindens on what they will be. I have heard no price differences will occur, I have heard that it will be 150L PER PE, that it will be 150L for the initial prim and 1L for each PE after and also 150L for the first and 10L for each PE after. Please confirm this, inquiring minds want to know! (Maxwell Graf)
#Users unlucky enough to have an NVIDIA GTX460 card on an older motherboard, under Windows 7 64 bit, (are) were unable to use any kind of recent viewer (released, snowstorm, mesh) because the infamous opengl error that plagues this card persistently shows up during login when shaders are turned on, since a specific point during viewer development two months ago. (There is a thread in the forum where we note the last Snowstorm/Mesh builds without the bug). (Edit: the solution at JIRA CTS-657 indeed seems to be working. But maybe this aggressive difference between these builds needs investigating. It's complex issue because it involves Nvidia drivers which are reportedly problematic.)(Angel Alphaville) (Comment by Tapple Gao: No; the change that was made is VWR-25931)
#I made two fixes to the collada importer (CTS-660 and CTS-744). How do I submit them for inclusion into the viewer? (Tapple Gao)
#Are we there yet?! Are you expecting mesh to roll out to the rest of the grid this week or next? [Vivienne Daguerre]
#Is there any difference between the server code of agni and aditi? I uploaded a model successful after 3 attempts to aditi, but can't get it uploaded to agni for 3 days now, it always ends with a crash whenever the viewer starts to calculate the PE and the other metrics (on Mac, which is still crashing a lot, btw) [Mikki Miles]

# Why do mesh objects have a +0.5PE penalty and a +1PE script penalty per object per linkset compared to regular prims which have none? (York Jessop)
# Can we have both physics and streaming cost displayed somewhere in the edit window? It was useful to be able to tell which was larger without having to go into the developer menu. (Brookston Holiday)
# (Perhaps related)When edit linked is checked, the number of prims gets updated in the edit window but the PE of the entire object is still shown. Is it possible to show the PE contribution of the one prim that has been selected, again without going into developer menu? (Brookston Holiday)
# What is the hidden agenda (assuming there is one) behind the new dropdown on the uploader that asks what the uploaded model is for? [Drongle McMahon]
# SH-2044 has been set to fixed, but the automated build at http://automated-builds-secondlife-com.s3.amazonaws.com/hg/repo/mesh-development/rev/237321/index.html doesn't seem to have the fix even though it's listed. It's likely a mistake on my part, but please confirm whether the fix is in or not in the install. (Raz Welles)
#I'm having problems getting the streaming cost formula to work. Is this wiki up-to-date? : http://wiki.secondlife.com/wiki/Mesh/Mesh_Streaming_Cost#LOD_Transition_Distances I read elsewhere that the LOD transition distances have different values now. Also, is "max_area=65536", "cost_scalar = 0.125" and is "radius = 0.5 * llSqrt(x*x + y*y + z*z)"? [Ashasekayi Ra]
#In the streaming cost formula, kbytes for each LOD are listed. Is there a way to approximate that value for ourselves offline since I assume this is a compressed value? [Ashasekayi Ra]
#You still can't have textures automatically load with a model exported from Blender 2.49. Is this a known issue? Or, does it need a jira? [Ashasekayi Ra]
#Adding a script to a linkset that has a PE count lower the the prim count results in rounding up to the prim count and voiding out any efficient mesh models that are below 1 PE in a linsket... why? My example was a 128 prim, 64 PE going up to 130 PE whit a "new script" added... [Moo Spyker]
#In the modernisation of SL, why has all effeort for new features seemed to be targeted at Mesh? I feel that the biggest immersion killer, and the area where SL is lagging behind other MMOs the most, right now is not having seamless sim crossings, and not being able to traverse the seas. [Davido Chrome]
#Please can you add to the Loginscreen from the Mesh Cleint Links to the mesh-wiki tips for handle the mesh upload. [bigjr Slade]
#When can we expect a viewer version that works with lion (macOS 10.7)? [Mikki Miles]
#Jira CTS-606 is marked as fixed, but it isn't. I made a comment, but i suspect nobody read it. So, on both my machines, MBP and a recent iMac I get a black screen when I try to display physic shapes, it would really be helpful to have this working [Mikki Miles]

# What's the current focus for the Mesh team? Where should residents focus to assist with testing new features?
# Bone lengths! Please give us an update on this.
# Presently, decomposing physics shape with multiple objects greys out upload button and prevents upload. Is this restriction intended? Will it remain through release? [Drongle McMahon]
# Will the mesh beta regions remain after release? If not, at which stage will they disappear? If so, for how long? [Drongle]
# Ensure physics type stays consistent between rezzes. Some meshes default to Convex Hull (even with a physics shape) when spawned by an object.
# When creating a partially-rigged mesh (ie: a shirt), how much of the skeleton rig is required in the dae? The whole thing? The relevant bones only? Everything from the hip up through the relevant bones? [bloodsong]
# If two rigged meshes are worn and both have custom bone length/positions, which settings will be used? [bloodsong]
# very strange behaviour on Mesh sandbox 20: new uploaded mesh rezzes as flat disc. sculpties do not rezz. Is that a known bug ? [Gaia Clary]
# Will fractional prim costs be used to calculate the total prim usage on a land (can there be actually more than 15000 prims on a sim ?) or will we always have to pay an integer number of prims regardless of the fractional cost ? [Gaia Clary]
# Not a mesh issue per se, but (IMHO) very related: Have you ever thought of also introducing fractional costs for sculpties with small sculptmaps ? e.g. make a sculpty made of 4*4 faces significantly cheaper than a sculpty of 32*32 faces ?
#(When...) can we expect to see a reliable prim-cost display in the object editor ? [Gaia Clary]
# Costs display: Even with the hover text it is not clear to me how much my prim actually costs. is it always the "cost:prims", or always the higher one of "cost:prims" and "cost:physics complexity" ? [Gaia Clary]
# Do you plan to add a generic import tool for ALL sorts of prims(regular prims,sculptes,meshes) similar to what is used e.g. by Phoenix as backup solution for regular prims and sculpties at the moment ? [Gaia Clary]
# If some third party would provide such an import tool for regular prims, sculpties and meshes, would that tool fall under the category "third party viewer" even if it has no graphical interface (no 3D viewer) ? [Gaia Clary]
# I'm trying to upload a model with 17968 tri and 13292 verts. The auto generated medium LOD counts 5988 tris and 5700 verts. I made a medium LOD with 2762 tris and 4853 verts, less than the auto generated LOD, but the uploader says "Level of details has too many vertices". It seems this message needs to contain some more information. [Mikki Miles]
# developer-> render metadata-> render physic costs turns my viewer window black and I can't see any physic shapes. [Mikki Miles]
# please add your agenda items here
