Lithos lithos.software
A collaborative terrain editor for games and film. In development; a private beta opens in 2026.
I’m Lewis Nelson, and Mestral Studio is me, working from the Scottish Borders. I’ve spent most of my career building developer tools. Lithos is the one I wanted for myself: terrain software tends to be powerful and hard work, so this is a professional-grade editor that keeps your attention on the terrain rather than the tool. One you can learn in an afternoon, and that doesn’t ask for a long-term commitment.
