- Chrome mapping different from Texture Mapping as the texture changes with a change in the view point

- hdri map: environment map displays a space background
  - HDRI or Environment textures
  - godot cubemap, reflection probe
- BRDF: Bidirectional Reflectance Distribution Function (face texturing)
  - reflection map, albedo, etc
