I know there is alot of excitement about the coming implementation of mesh and I look forward to making more detailed works in SL too. However it is very important that we understand mesh will not nor should not push out the use of prims nor sculpts. The fox you see here is a total of 7 prims. If it were done in mesh it would likely rise to around 500 prims because currently the size of your work as a mesh varies the amount of prims they will cost. The benefit in making this fox worth only 7 prims while being on megaprims is a huge benefit over mesh at the moment. So lets keep that in our arsenal of tools when building. But a sculpts overall value will diminish greatly if they end up looking like blobs to the vast majority of users. Because you buy a large nail doesn't mean you should throw away all your little nails and screws.
Another thing to consider about sculpts is that a huge portion of the economy from fashion to furniture is now based off of sculpts. People will not like the idea of replacing items because things suddenly start looking less appealing. As well many of the artworks in Second Life will suffer the same problem.
On phoenix viewer, in the bottom right, is a scalable tool to rise or lower LOD. It's not hard to find and easy to change. On viewer 2 and Firestorm I have yet to find where to adjust the LOD setting and I am an experienced user. A new user will never find the LOD setting before they determine whether they wish to stay or not. I spoke to Jessica Lyon (Phoenix/Firestorm viewers) the other day about this and they will be increasing LOD to 2 or 2.5 for the next update, but a similar attempt to speak to Torley Linden has not been successful. Thing is I have no idea who to contact about this at Linden Lab so that is why I am writing this post. Also while I am at it please add the multitude of windlights to Viewer 2 and revert the way we adjust windlights back to how they originally were. Right now I can't edit any default windlights even slightly which is a huge problem for machinimatographers. Sometimes you just need to lighten a windlight or make a minor change which takes seconds but unfortunately now you must create a whole new windlight.
