What goes in the kiln

Mesh editing

Select vertices, edges or faces on the object in-world and move, extrude or cut them.

In development

12 faces selected

Texture painting

Paint straight onto the face in-world, in layers, with base colour, roughness and emission. Try it on the tile above.

In development

UV editor

Unwrap, pack and see the seams on the object while you work, not in a separate program.

LOD and physics

Generate all four levels of detail and the physics shape, and read the land impact before you pay to upload.

Planned

Try before upload

Wear and rez your work locally, with your own textures, until it is right. Upload once, at the end.

Built on the official viewer

Kiln starts from Linden Lab’s own viewer and follows its releases, so new Second Life features arrive with each merge. It keeps its own settings and cache, and runs beside Firestorm or the official viewer.

A domed beehive kiln firing bricks, with a tall chimney behind it.

A kiln is where shaped clay and wet glaze become one finished piece. That is the step Kiln brings into the viewer.

Common questions

  • Yes. Kiln is free, and its source is released under LGPL-2.1, the same licence as the viewer it is built on.
