Cold Sweat: Altitude

Cold Sweat: Altitude is a Cold Sweat addon that makes the world’s temperature change with height.

It was designed with Create: Aeronautics in mind: a climb in an airship should feel different from travelling at sea level. As a ship rises, the air can become colder, more exposed, and eventually dangerous without the right preparation. The same system also gives modpacks control over caves, mountains, and every layer in between.

Requires Cold Sweat 2.4.4 or newer.

Features

• Define warm underground layers, temperate surface conditions, cold mountains, and hazardous upper skies
• Create smooth temperature changes between altitude layers, rather than abrupt jumps
• Add wind exposure to high-altitude areas, making open-air travel more dangerous
• Sew Windproof Lining into armour at Cold Sweat's Sewing Table to prepare for exposed flights
• Let shelter reduce altitude and wind exposure, whether on the ground or aboard a ship
• Fully supports Create: Aeronautics, so altitude temperature and wind continue to matter while flying on assembled ships
• Keep Cold Sweat's usual biome, weather, thermal-block, hearth, and insulation systems working alongside altitude effects
• Give players clear, colour-coded feedback as they move between altitude layers

Cold Sweat: Altitude is built for pack makers who want vertical travel to matter. Use it to make mountain expeditions require preparation, make caves feel distinct from the surface, or turn a high-altitude flight into a real survival challenge.
