It goes without saying that not much good can ever come out of that.
How to use ac3d to make mesh for second life generator#
The uploader's generator is based on GLOD of all things - apparently it's even a rather sipmlistic and outdated application of GLOD. On top of that, the uploader includes a feature to generate those LoD models automatically and many use that because they don't know better or because they can't be bothered to make them properly. There is no way to adjust the LoD switch points for individual items to what is actually suitable for that specific case. There are three of them and they are applied at view distances determined only by object class and bounding box size. But it's also a rather crude and primitive system of LoD models too. Obviously, with a 15 years old game engine there's no Umbra and no tesselation or anything modern and fancy like that, it's all done with LoD models. The other factor is how SL handles level of details. Unfortunately, the skill level of SL content creators - even those who regard themselves as professionals and make a living here - tend to be quite low compared to what you generally find in the 3D industry so most of the content is very poorly optimized.
That means that optimization is even more important here than anywhere else. For more mesh heads and bodies head on over to The Mesh Directory. For a super in depth look at everything to do with this body check out this in depth post. One is that SL scenes tend to be far more crowded with content than games scenes and such and people still want and tend to expect the same level of performance. This is an overview of the Inithium Kupra mesh body for Second Life avatars.
But if you have modelling experience from other environments and not Second Life, there are two special factors you need to be aware of. Second Life CopyBot Forum is a place where you can get items for Second Life and other vitual worlds for free.
Yes that is the same with any program employing a render engine.
