Learn how to fake 3D corridors, rooms, and pipes inside a simple flat quad using custom HLSL and Unity Shader Graph!
This interior mapping / parallax illusion allows you to create non-playable spaces without adding a single extra vertex to your scene, saving massive rendering performance.

⚙️ WHAT YOU WILL LEARN:
- How ray tracing on a flat quad fakes 3D geometry depth
- Setting up custom HLSL functions in Unity Shader Graph
- Creating a Fake Box Corridor with custom room scale & offsets
- Implementing room-space lighting & scene main light support
- Adding depth fog to sell the visual illusion
- Faking circular 3D tubes using Alpha Clipping & Masks
