This is a demonstration of a Catacombs 3D map rendered on the surfaces of prims each prim has 8 faces and is 8 pixels. This required unlocking the FASTEST Opensim possible settings. Settings not exposed by opensim. This made it possible to script a walkable 3D FPS map crypt with fake lighting effects all just colors! no textures. It is grainy because is extremely low pixels!
A technical marvel for opensim that it can indeed run DOOM on a prim if you was to script it. For those who think its fake i will be opening a special region called Limits in Winxtropia with the demos soon!
