Underground Adventure

Venture underground into the dark mines and seek fortune!
Underground Adventure is a modular environment pack developed for first person games.
Combine ready-made tunnels and rooms together or create your own using base components.

◈ COMPATIBILITY ◈

Underground Adventure requires Unity URP 2019.4+

The Visual Effect Graph package is required for particle effects, it should be installed through the Package Manager.

Amplify Shader Editor can be used to edit our custom shaders but is not required to use them.

This pack works best with “SRP Batcher” disabled and “Dynamic Batching” enabled. Those settings can be found in the Universal Render Pipeline Asset, under the Advanced section.

◈ FEATURES ◈

• 227 base prefabs and 22 pre-assembled tiles prefabs
• Easily snap tunnels and rooms together, building your underground cave network
• Engineer structures with floor, panels, stairs, planks, ladders, ropes and various supports
• Place tables and tools as work stations
• Bring the environment to life with lots of plants and roots
• Add some grit to your scenes with torn rags
• Make it spooky with spiderwebs and skeletons
• Plants, rags and spiderwebs move softly in the wind
• Light up your levels with torches and lanterns
• Connect rails and use minecarts to transport rocks
• Use animated chests as loot boxes or for inventory
• Add some rock formations and rubbles
• Place glowing transparent crystals to dig
• Use ambient dust and fire particle effects
• Custom crystal, foliage and scaled UV shaders
• Custom Bokeh bloom texture for camera effect
• All prefabs have been setup with collisions
• Demo scene included

◈ Prefabs ◈

Prefabs have been saved into "Base" and "Tiles" folders. Base are individual prefab objects, Tiles are composed of multiple base prefabs.

Tunnels and Rooms can easily be snapped together using the "Grid and Snap" Unity feature with a Grid size set to "2.5".
The Grid and Snap panel can be accessed from "Edit > Grid and Snap Settings..." and can only be toggled on when the Tool Handle is set to "Global".
