• With cats
• RTX on!
  • Do as much as possible with RTX?
  • Shadows? Ambient occlusion? Global illumination and hardcore caching? SDFGI?
• Global illumination (and probably no shadow mapping)
• Windows, with a sun and godrays
• Normal mapping for walls
• Deferred shading
• SSAO
• Bloom for windows where the light enters
• Multiple directional lights from the outside! No light sources inside the scene.
• PBR
• HDR
• Doors = windows, very bright. When you walk through them, you are temporarily blinded (see eye adaption/HDR exposure).

For starters, we might as well use https://github.com/mxgmn/Blog/blob/master/Escheresque.md

I could make the models myself in Blender (modular ones), and use a brutalist, concrete style. That way, I can get away with low poly textures. A certain sci fi style would also be doable, but it's more work.

Portal/window rendering can be done as follows

1. Windows have a solid geometry where their holes are. That solid geometry is specially marked, and will be used for cool tricksies.
2. The scene is duplicated. (Like manifold garden)
3. Rendering works as follows: We first render the window hole models to a texture.
4. Then we render the scene (excluding the window hole models).
5. During scene rendering, we use the window hole texture to decide whether to render more models, or if we should render the skybox.
