1: OA Sandbox Platform; 2: Calleta InfoHub; 3: Cleveland Plus III; 4: Second Latte Coffee Co.
The OA Sandbox is much used location and one run by the Green Lantern Corps. The platform is just above this at 800m, and is generally used for large buildings. I found this a good location to rez D'Olby's Base for shoots, though I sometimes went to 3000m using the "EZ" Magic Chair. Calleta InfoHub is longstanding Sim in Second Life and a favourite of mine for shear character, and the fact that railways are a big thing there. It's also full of Arcadia Asylum stuff which you can copy and mod. In practise I found the shear number of textures and scripts there made it laggy as a shooting location, so I only used it for Elsie's return. Cleveland Plus III is part of Cleveland 2.0 which includes several Sims and is run by Case Western Reserve University. I used it as a stand-in for Praxis U. The Second Latte Coffee Co is a nice café I found for one of the final scenes. No one was around when I shot one of the final scenes there, and it seemed like a pleasant place to have a chat with friends.
