From Second Life Wiki
Mesh is the capability to bring 3D models, known as meshes, created in third-party tools into Second Life.
To upload and render mesh content, you need a mesh-enabled viewer, such as the official Second Life Viewer.http://secondlife.com/support/downloads/. If you are using a third-party viewer, check its documentation to see if it supports mesh.
If you don't already have a mesh-enabled viewer:
- Download the Second Life Viewer from Second Life's Downloads page.
- Install and run the Viewer.
To upload mesh content you must complete the mesh tutorial and have payment information on file:
To try out mesh:
- Go to one of all the sandboxes in Second Life. See Second Life Public Sandboxes.
- Some sandboxes may become overcrowded with Residents and have poor performance. If you see objects that look like a lot of flat triangles, try moving to another region.
- See what people have been working on, or try uploading some sample content of your own!
- Prims, Prim Equivalent, Land Impact... a too long guide An in-depth exploration of land impact, originally posted by Jenni Darkwatch in the Mesh forum.
