Inside Endless Powder: fully procedural terrain, snow interaction and audio

On October 22, developer sterlingcrispin posted a series of threads breaking down the terrain generation design of the skiing game Endless Powder. The core idea: "a level is a recipe, terrain is math" — each stage is a recipe-style formula combining coordinate fields, chapter parameters (density/scale/branching), and local terrain features, with the vast majority of terrain generated mathematically rather than from static assets.

Confirmed

• There are 32 standard recipes split into four families of eight variants each, drawn with seeded selection to avoid back-to-back picks from the same family; chapters change how opportunities and obstacles are distributed across the same mountain, rather than loading prebuilt levels
• Terrain is built on a continuous mathematical field controlled by shared cubic B-splines, with local curvature and slope driven by classification; half-mile chapters complete their transitions within roughly 200 meters
• Levels are not random collages: they go through a "place–generate–test" pipeline that accounts for global factors like the full run line and spacing between trick-able obstacles, ensuring procedurally generated hard terrain always has a viable path
• Inspired by Corbet's Couloir, The Chute is a signature high-feature hazard: the mountain abruptly steepens and players must thread between massive rock walls; the first Chute appears in showcase chapter 04 and recurs every nine chapters after

Why it matters

This series of posts lays out a complete infinite-terrain approach built on "recipes + continuous math fields": it guarantees variety on every run (seeded recipe draws, parameterized combinations) while a global testing pipeline preserves rideability and trick space — a valuable reference for procedural level design.
