In game engines like Unity or Unreal Engine , developers often package (trees, grass, bushes) into .7z archives.

Knowing if it’s for a specific software (like a game mod or a design project) would help me provide more exact details or instructions on how to use the contents.

This likely includes high-resolution textures (PNG/TGA), 3D models (FBX/OBJ), and shader files for realistic plant life.
