Correction (changed or unsupported figure). C3-B012-W4-06 says the demo builds meshes from a '1920x960-class' equirectangular panorama. In the pinned world_composer.py the default working resolution is 3840 x 1920 (width, height), the foreground and background mesh resolution caps are 3840, and only the sky mesh cap is 1920. Input panoramas of another size are resized to the configured resolution. The 1920x960 figure is therefore not what the cited file defines, though the 2:1 aspect is right. Version/date. Pinned commit 57fa9f3 fetched 2026-10-23.
