Short how-to videos for the R3 editor, one task each: randomize a terrain, change a material's colour, change a light, put a texture on a mesh and attach physics. Each has captions, chapters and the full transcript, and the physics and texture tutorials now show theirs at the top.
The same steps are written down for Claude too, so when you ask it over MCP for terrain, materials, lights, textures or physics, it follows the same steps you see in the video.
Watch them all at r3js.org/videos/how-to.
