Harappa:
A Free Blender Add-on

On November 14, 2026, we released Harappa, a free Blender add-on, as open source on GitHub. Harappa (harappa means "meadow" in Japanese) builds an anime-background meadow: grass, flowers and sky with one click, and trees with one more.

Every tuft of grass grows on its own and sways in the wind, while light and shadow fall in big painted clumps. Trees are made of brush-dab leaves in nine shapes, from round trees and cherry blossoms to pines, willows and poplars, and the sky gets solid painted cumulus and layered distant mountains fading into the haze.

Mix six seasons (summer meadow, spring blossom, golden hour, autumn leaves, moonlit night and misty morning) freely with four styles (Anime Background, Painterly, Crisp Cel and Soft Pastel). Every press of Shuffle changes the tree shapes, the clouds and the flower colours.

Paint paths, flower beds, tall grass and sunlit patches with a brush, and let the grass make room for your characters and rocks. Give any tree, cloud or meadow its own colour, and save the colours you like as a Look to use in any file. The interface is in Japanese, English, Simplified Chinese and Korean. Just ask an AI agent such as Claude Code or Codex, and it installs the add-on and builds the scene for you. The images and videos you make with it are yours to use, commercially too.

Harappa is our fifth Blender add-on, after MochiToon, KiraPaint, Painterly 2.5D and Senga Sketch. Everything we have released so far is on our open source page.

We will keep refining the tools that come out of our own game and film production, and keep releasing them.
