It seems you can’t keep a good viewer down as new third-party viewers have popped up with updated mesh support. Astra, Catznip, and Niran have joined the family this September, providing an alternative to SecondLife’s Default viewer.
Catznip, created by Trinity Dejavu and Kitty Barnett is an a user-friendly third-party viewer which is based on the original V2. According to Catznip’s blog Catznip 2.6 & 2.8 were released on September 20, 2011. Catznip seems like the Imprudence of V2, keeping things simple and does not over complicate the user experience. The Torch SL Guide recommends this viewer to first time Second Life users.
Niran’s Viewer is a German Based Viewer and is a Kristens Viewer modification. After discontinuation of the Kristen viewer, Niran developer NiranV Dean started on Niran’s blog :
