Description
IMPORTANT!! Pack Requires The Base Asset:
Victorian Mansion Environment
“Mysterious Mansion – Level” is a high-quality, game-ready interior level set in a detailed Victorian mansion environment. It features 19 unique, fully furnished rooms and corridors with consistent lighting and decor, designed for use in horror, mystery, or exploration games.
This asset provides a hand-crafted, production-ready level that can save you dozens of hours of environment design, set dressing, and scene optimization. Although it does not include individual 3D models, the entire level is fully assembled, lit, and structured – allowing you to:
Prototype faster by dropping in your gameplay systems and using the environment immediately
Focus on game mechanics instead of spending time on level layout, decoration, and lighting
Use it as a reference layout for your own interior level design
Replace or swap props with your own models while keeping the spatial design and logic intact
Test lighting, atmosphere, and gameplay scenarios in a complex, performance-optimized interior space
It’s ideal for solo developers, small teams, or anyone needing a plug-and-play interior with baked-in logic and scene structure.
This package includes several ready-to-use scripts:
Door Controller – script that allows the door to be opened by pressing key and closed automatically when the player leaves the designated area.
Light Optimizer – script that turns lights, shadows and volumetric effects on and off when the player is at the appropriate distance.
Room Triggers – script that activates and deactivates rooms when the player approaches or moves away from them.
Character Controller – simple character controller to test the scene. (works with old and new input system)
Additionally, this asset adds candle and fire flames, and includes several new prefabs based on the prefabs included in the Victorian Mansion.
The entire scene has been thoroughly tested:
– no missing colliders
– no lighting artifacts
– no console errors
– optimized for 60+ FPS on GTX 1060 (without using occlusion culling, GPU instancer etc.)
