Sci-Fi Low Poly Interior Bundle: Grand Colony Collection (5-in-1) | Cosmic Retro


The Grand Colony Collection represents a massive leap forward in the Cosmic Retro universe. By integrating five specialized sectors—Station, Mess Hall, Laboratory, Hangar, and Bedroom—I have created a comprehensive worldbuilding system that allows you to design entire lunar outposts or deep-space facilities with absolute aesthetic cohesion.

This is not just a collection of assets; it is my personal vision of a lived-in, functional space colony where every module tells a different story—from the cold efficiency of the research labs to the cozy, personal sanctuary of the crew quarters.


Inside the Grand Colony (5-Module System):

  • Bedroom Sector (Living Quarters): A personal sanctuary featuring bunk beds, modular lockers, and personal clutter (books, mugs, guitars) to create a "lived-in" feel. Includes 103 unique models and 122 prefabs.
  • Hangar Sector (Maintenance Hub): A technical space for transport units featuring cargo bots, drones, and fuel stations. Optimized with 92 meshes and prefabs.
  • Laboratory (Research Sector): A high-tech environment for scientific discovery with medical beds, retro computers, and control stations. Includes 52 meshes and prefabs.
  • Mess Hall (Social Zone): The heart of the colony where the crew finds respite. Includes vending machines, consoles, and modular walls/floors. Optimized with 92 meshes and 104 prefabs.
  • Station (Command Center): The operational nerve center of your base with interactive utility consoles and openable crates for loot mechanics. Features 89 meshes and prefabs.

Technical Excellence for Creators:

  • Modular Construction: All sectors include modular walls, floors, and structural elements designed for perfect grid snapping.
  • Extreme Optimization: Utilizing minimalist texture atlases (8x8 px to 16x16 px) to ensure your project stays lightweight and VR/Mobile-ready.
  • Developer-Ready: Every asset features clean topology, custom pivots, and built-in colliders for an effortless creative workflow.
  • URP Demo Scenes: Includes individual, pre-arranged demo scenes for each of the 5 sectors to showcase the unique mood and lighting of every module.

Technical Specs:

  • Engine Support: Plug-and-play for Unity (URP default), with included setup files for HDRP and Built-in.
