General Info

TL;DR: I've made a UE4SS script that moves the camera around and captures the RenderTarget into tiles.

• The whole thing is described in details on the wiki here: https://github.com/joric/subnautica/wiki/
• Reddit: https://www.reddit.com/r/subnautica/comments/1tqt0uz/subnautica_2_map_in_full_128k_resolution

Processing a 128k tileset took about 150 GB of scratch space on disk. 256k would need at least 4x more for all the raw bitmap layers and alpha data. Fast SSD helps.

Tilesets

Capture V1

• Alpha version. Uses TileCaptureRT_v1.lua, montage_16x16.cmd, make_tiles_vips.cmd (see scripts directory).
• Source tile size 2048p, grid 16x16, chunk size 25600. Centered on observatory.
• Map bounds in chunks (multiply by 25600): {left:-17, top:8, right: -1, bottom: 24}
• Destination tile size 512p, 6 zoom levels (32k map).
• See https://github.com/joric/subnautica/wiki/ for details.

Capture V2

• Script in question: https://github.com/joric/subnautica2_tileset/blob/main/scripts/TileCaptureRT_v2.lua
• Building tiles: https://github.com/joric/subnautica2_tileset/blob/main/scripts/CaptureConvert_V2.cmd
• Map image: 131072x131072 pixels, 512 px tiles (webp with alpha, 75% quality), 38397 files, 403 MB total.
• Map size: 32x15 chunks (4096 x 4096 pixels each), 9375 units each, 300000x140625 units, ~ 3 x 1.5 km.
• Total map size (approx.): streaming textures vs ea map ~ 16384px / 2400px * 3 km ~ 20 x 20 km total.
• Area coverage: ~ 4.5 km2 / 400 km2 ~ 1.1% of the total area.
