Catacombs - Retro Style Modular Environment Pack

Create underground burial corridors, crypt chambers, and dark fantasy catacombs with a modular system of 270+ prefabs designed for grid-based level building. Build niche-lined tunnels, skull-decorated passages, arched corridors, coffin rooms, and atmospheric underground spaces using modular walls, ceilings, pillars, arches, tunnels, and decoration presets.

Catacombs features a distinct low-resolution texture style, combined with crisp filtering, creating a unique aesthetic that blends retro charm. It captures a nostalgic feel without the limitations of old game engines or consoles.

The included demo scene showcases a fully assembled catacomb environment, providing a ready-to-use setup and a strong starting point for your own levels. A separate prefab showcase scene is also included for easy asset browsing.

TEXTURES AND MATERIALS

• 17 low-resolution textures and materials, including stone, bone, wood, metal, and flame FX.

Materials are prepared for the Built-in Render Pipeline and can be easily converted to URP.

Converting to URP

• Select all materials (they should appear magenta), from the top menu, click Edit > Rendering > Materials > Convert Selected Built-in Materials to URP.
• For Unity 6, open Window > Rendering > Render Pipeline Converter. Select the Built-in pipeline as the source and choose your target pipeline. Select “Material Upgrade,” then click “Initialize and Convert.”
• Ensure all textures have their Filter Mode set to “Point (no filter)” to prevent blurriness.
• Texture Compression should be set to None.

No custom shaders are used. Materials are compatible with URP and HDRP, though HDRP has not been explicitly tested.

NOTE: Some materials use double-sided rendering in URP. In the Built-in pipeline, the Particle/Standard Surface shader is used to achieve double-sided behavior.
