Mirrors, PBR Terrain, and 2K textures

Second Life is getting some new, exciting features that will make the world look even better.

Mirrors are arriving soon! While we love the realistic reflections PBR materials enable, mirrors take reflections to a whole new level.

You can create a mirror using a method similar to reflection probes, but with a twist -- when a reflection probe is set to use the “Mirror” option, all surfaces near the probe will exhibit a real-time mirror reflection, including PBR and legacy materials.

We chose this method to enable maximum flexibility.  For example, you can create a big wall of mirrors and have minimal performance impact regardless of how many mirrors are on that wall. As long as they’re aligned with the mirror reflection probe, they can all show a mirror reflection.

To conserve performance, mirrors are subject to some limitations. The Viewer will show the effect of only one mirror reflection probe at a time -- the one closest to your camera. Mirrors are planar, so they won’t work very well on the body of a car, for example. Like so many good things in life, mirrors are best enjoyed in moderation.

Applying PBR materials to terrain will be possible in the upcoming featurettes release. You will soon be able to apply most GLTF materials to terrain. Initially, PBR terrain will support normal maps and metallic-roughness maps. Emissive textures will not be visible on some machines and transparent materials are not fully supported. We expect PBR materials on terrain to vastly improve the beauty of SL -- because there’s a lot of terrain out there!

PBR terrain uses triplanar mapping, a texture-mapping technique which is new to Second Life. On steep slopes you will notice far less texture-stretching. To conserve performance, triplanar mapping will be enabled only when the graphics quality setting is set to “High” or greater.

With the advances in GLTF PBR Materials and upcoming Terrain materials, we know it is time to increase the texture size limit to 2K (2048x2048 pixels). We are approaching this change  carefully, and are still weighing pricing options for images larger than the current max size. 2K textures will allow artists to add significantly more detail to their creations and do things like efficiently consolidate more UV surface area onto a single asset.

Mirrors and PBR Terrain will be available on the Beta Grid (Aditi) to start with, on the following regions:

  • Rumpus Room 2048
  • Rumpus Room 2049
  • Rumpus Room 2050
  • Rumpus Room 2051

We can’t wait to see what fun and exciting new things residents create with these featurettes!
