# Prototype environment maps

`studio-small-03-1k.hdr` is the 1K HDR edition of Poly Haven's
[Studio Small 03](https://polyhaven.com/a/studio_small_03), created by Greg
Zaal and released under the CC0 license. It is kept locally so the prototype
does not depend on a third-party request at runtime.

`studio-small-03-512.hdr` is a linear-HDR 512×256 derivative made in Blender
for the realtime prototype. The 1K file remains the source reference; the
smaller derivative is the file loaded by the browser.
