We could just package this texture set (and others) into base data included when installing trem, as a shared texture packs(s) (pk3 dependencies) instead of using “default” map texture sets and maps depending on other map
Pk3s. Any texture sets from the map(s) used to assemble a shared texture pack would be reconfigured to use the shared pack, leaving just a bundle of bsps, external lightmaps (hopefully) and config files to distribute as the “default” maps.
r_lightmap 0 ?
Try the following: r_fullbright 0; r_lightmap 0
