One advantage of the new architecture will be that Linden Lab will be able to upgrade a few servers at a time and that clients will also be able to move to new viewer software at their own pace. If we decide down the road also to potentially allow less restrictive open-source licenses, it's easier to go in that direction than to have started with, say, the BSD license." It is, in many ways, the purest of the open-source licenses. "The GPL.gives us the most options down the road. "It was the conservative decision and gives us the most options going forward," Ondrejka said of the licensing decision. That means that moving to GPL 3, due in March and at the center of some open-source controversy, would require an active decision by Linden Lab. Like MySQL and the Linux kernel, the Second Life viewer is licensed only under version 2 of the GPL, Ondrejka said. With Linden Lab owning copyright, it will be permitted to change licensing terms if it desires.Ĭhanging licenses is a very real issue. Programmers must sign a contributor agreement to submit code.īy signing the contribution agreement, a programmer agrees to assign joint copyright to Linden Lab and grant Linden Lab and anyone who receives the code a patent license relating to use of the code. Now that Second Life needs lights to illuminate rooms and interior spaces that use manual reflection probes, we’re going to reduce the download cost of objects by 15%, across the board, without any additional charges, which will create more available Land Impact for everyone.Linden Lab will vet all outside contributions and maintain control of an official version of the viewer software, the company said.

We can’t wait to see what you all create! In the remainder of this post, we have included some more technical points for creators. Whether you create objects in Second Life or simply enjoy seeing and wearing them, PBR Materials will provide a big step up in the appearance of the Second Life world. One method of enhancing realism is to create scenes with real reflections which mimic how our eyes have learned to identify that a surface is metal, plastic, or some other material. The goals behind the PBR Materials project are increased visual realism, keeping with industry standards, and bringing GLTF content into Second Life with expected results. Today is the official release of the literal new shiny in Second Life, PBR Materials! With our weekly grid update, all of Second Life will now be capable of using PBR Materials in the Second Life viewer.
