EOTB: New "Second Life University" Video, "Introduction to .glTF"

 

In November, the Second Live University videos resumed after a two year hiatus. Late last week on January 8, Linden Lab announced it's latest one, "Introduction to .glTF."

Class is back in session! Second Life University returns with a special new episode featuring AxlTruth (Mesh Monster). We are excited to welcome him to the series!

In this episode, Axl walks through one of the most important updates for content creators, .glTF and PBR materials. With .glTF, you can import a full PBR asset, including mesh, textures, materials, and rigs, using a single streamlined workflow.

Axl starts with a quick breakdown of what .glTF is, why it matters, and how it works alongside physically based rendering (PBR). He then demonstrates how to set up materials in Blender, export a .glTF file, and bring it into Second Life. You will also see how to import materials, manage the level of detail and land impact, and apply textures efficiently. The video wraps with the same workflow using Substance Painter, making it easy to bring fully textured assets into Second Life with consistent results.
