Build Fake Interior Spaces Behind Flat Surfaces With This Unity Tool

You've likely seen developers creating the illusion of interiors in their games on our site or elsewhere, and now you can do it too with Real Fake Interiors. It's a parallax interior shader and baking tool for Unity that lets you simulate a fully furnished room behind any flat surface using just one set of baked textures and a single shader, with no extra geometry or draw calls.

It works by raymarching baked depth data at runtime to create interior parallax, blending a baked cubemap for the room shell, and compositing the result into the final image. One bake works across the Built-in Render Pipeline, URP, and HDRP, so you're not locked to one setup. Just place your own assets in the room and bake it with a single click using the tool.

For best results, it's recommended to use TAA, although the system also works without it. Performance can be improved by using lower step values for distant objects. Real Fake Interiors are an approximation rather than a 1:1 representation of the original assets. While the asset reduces polycount, CPU usage, and draw calls, it does increase GPU cost, and in some cases, it may be more expensive than standard POM. To optimize performance, especially for distant windows, use lower texture detail, fewer parallax steps, and LODs where appropriate to reduce overall shader cost.

Please note that this is a shader and baking tool combo, not a pre-made interior collection pack.
