The limits for building are established by the platform. In OpenSim, Hippo is capable of building prims as large as 256x256x256. However, SL supports prims only up to 10x10x10. Therefore, while using Hippo in SL, you will not be able to set prim dimensions beyond 10x10x10.

The documentation currently available or being worked on includes:

• List of Changes
• Platform Limitations
• Build instructions for Windows
• Build instructions for Linux

The Hippo OpenSim Viewer is a modified viewer, targeted at OpenSim users. It allows building up to a height
of 10,000 m, scaling prims up to 256x256x256 m and other exciting features. More specific OpenSim features are under development.

The current version is based on the official Linden Lab release 1.21.6.

NOTE: This viewer can connect to the Second Life grid, but there the usual limits of Second Life apply.
