General Info

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

• The whole process is described on the wiki here: https://github.com/joric/subnautica/wiki/

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

• To fix alpha edges use resize instead of thumbnail, vips resize a.v alpha.v 32 (force pushed on Jun 1 2026).
• 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.
