STYL-Underground Prison Unity
STYL-Underground Prison - Stylized Modular Dungeon Kit
Overview
STYL-Underground Prison – a stylized modular dungeon kit has been designed so you can build a medieval underground prison environment in a modular way.
- Each module is designed in 2m units. In Unity, you can freely place them using the snap function, set to 1 unit.
- Includes easily assembled walls, floors, pillars, props, etc. for use in Unity, allowing you to create a variety of prison environments.
- Optimized for top-down, 3D action RPG, and roguelike games, making it suitable for multiple genres.
This guide is intended to help you quickly understand and effectively use the asset.
STYL stands for Stylized Theme, Your Level, a series of high-quality assets designed to help you efficiently create stylized environments.
We developed this series to maintain consistent quality and style across stylized assets. We’re starting with a medieval theme, but we plan to expand to sci-fi, modern, and more in the future—so stay tuned!

Units
The STYL-Underground Prison asset is created with 2m units for flexible structure construction. Since Unity treats 1 meter as 1 unit, setting your Grid Snap to 1 makes placement much easier.
Using Snap
-
Click the Snap Increment button at the top of the Editor.
-
In Increment Snapping, set the Move value to 1.
-
Select the desired object in the Scene view.
-
Move the object while holding down the
Ctrlkey.
-
The object will snap according to the value you set.
Prefab Naming Conventions
STYL-Underground Prison uses a consistent prefab naming convention for systematic asset management. This approach makes it easier to identify each asset’s type, features, and variations.
However, not all assets may perfectly follow this naming scheme. Some objects may share common materials and textures across multiple assets, leading to minor naming adjustments for organizational purposes.
Even in these cases, we strive to maintain consistency.
Naming Format
Each prefab name follows the format below:
[Prefix]_[Category]_[Descriptor]_[Variation]_[Additional Info]
| Component | Description |
|---|---|
| Prefix | SM (Static Mesh) |
| Category | Main type of asset (e.g., Stair, Pillar, Prop, Trim, Wall, etc.) |
| Descriptor | Describes shape, style, or function (e.g., Spiral_Slide, Rough, Round) |
| Variation | Distinguishes different versions of the same asset - Numbers ( 01, 02, ...): minor shape differences - Letters ( A, B, C, ...): major shape differences |
| Additional Info | Details like size, alignment, angle, etc. |
