I'll go ahead and bite and respond to this thread. Mesh to me sucks. Let me count the reasons why....
1. Alpha layers, most shoes now use alpha layers, I have to take off the alpha layers for mesh which means some weird shoe options unless I'm missing something. If phoenix allows multiple alpha's someone can share how, because I would love to know how.
2. Lack of viewer support. For whatever reason, LL felt the need to shove mesh out, knowing full well that the majority of the grid couldn't see/use/interact with it. That's great, but it also creates a ton of users walking around thinking they look awesome in the latest fashions who look like total dorks with huge spheres around them because they will have to pry phoenix out of my pixel hands. Based on the massive number of people I've seen using phoenix still, seems I'm not alone in this.
3. I kinda like my shape, I've tweaked it over years and I'm rather fond of her. I don't want to look like barbie just like everyone else to fit into an outfit that someone else created. I think I know the reason why most mesh outfits don't fit properly, the designers are using the default avi mesh, which is TINY if you have ever looked at it. That's something that's a huge difference to the actual avatars that are in world, and as such creates some serious fit issues. If someone has actually exported a realistic shape to use in the program then fit would be much better.
Currently I'm just sitting back and watching mesh, the SLINK boots are tempting but sorry not worth giving up my fav viewer for. I've tried using v2, it blows, and Firestorm while better is still a whole lot like v2 and has a few bugs that as a creator make it really, really difficult to work with. LL seriously screwed up when they released v2, and should really scrap the project and start over and just cut the huge financial losses of v2.
