Next Steps for Mesh Import in Featured News A group blog by Secondlife in General Posted September 15, 2010 The current SL head is under 1000 vertexes. The entire SL avatar is roughly 3400. Even if you want to use a head with that much geometry you will still have to chop it down for your LOD. If you are starting off at roughly 3k, then your first LOD will be around 1.5k, then in the 700s then in the 300s. You are of course free to let SL chop it for you, but they will be using a very similar algorithm to do it anyway. In any case, my point stands that automated remeshing systems are not particularly useful when making low poly models. Also, there are no hard numbers that I know of, but I seriously doubt that one prim will equal 4096 vertexes. The best information I have seen so far indicates that you are off by an order of magnitude or more.
