While not a ton out there yet when I looked what little profesional looking mesh I saw was absolutely fantastic. It actually makes older geo prim and sculpt builds look like 1980s PC games that is how much better some of the stuff is.
That said, it will be the death of Second Life if they do not fix the V2 style interface (meaning get rid of it completely, entirely, not keep a single thing from it). I have been in SL since 07 and I am telling you when I try a V2 (or v3 for the mesh) viewer including firestorm I feel like an absolute newb. It is unusable. Yeah the stability needs fixed but that will obviously come, its the UI itself that is the problem. I cannot describe how much I despise the v2 style UI. yes, actually I can. Whoever came up with it should be fired, and never ever design another UI in their life. That is how bad it is. How utterly unfunctional it is. LL is like a 4 year old when it comes for this stupid viewer. Since its inception people have been telling them its crap and here we are a couple years later and it is still the same basic UI that V2 started with.
My wishlist? Is for the phoenix / firestorm people to find a way to include all the functionality of V2/3 that LOOKS in the style of V1. Foreget what changes have been made to firestomr, I have watched the youtube of how to make it function more like phoenix. It is not enough. It is still way too unintuitive to see when you have a group or private IM. The top section of the interface needs to be removed completely. I do not want that stupid search bar up there. Nor do I want pictures for my buttons. Just put the darn text on them like V1, why is that so difficult to have?
Ok rant over, V2 just frustrates me that much.
