## Game Base

What does Monster Hunter Wilds define about the ecosystem, and how does it affect the skin appearance of players and NPCs?

1. Ecology Phases : The base game defines ecology phases, but they have no direct effect on the skin appearance of players or NPCs.

2. Regional Terrain : The base game defines the terrain characteristics of each locale. In practice, only water exposure has a noticeable effect on skin appearance. This behavior lacks a broader environmental simulation.

3. Time of Day : The base game defines time progression, but it has no direct effect on skin appearance.

4. Extreme Weather : The base game includes only four extreme weather types: Sandstorm / Blizzard / Heatwave / Heavy Rain, Among them, only Heavy Rain and Heatwaves have visible effects on the skin of the player and the six Support Hunters. The other weather types have virtually no visible skin impact.

5. Settlements and Safe Areas : Base Camps, Villages, Settlements, and the Grand Hub do not provide any skin-related environmental effects. The points above represent nearly all environmental skin interactions available to the player and the six Support Hunters in the base game. NPCs found in settlements, villages, camps, and the Grand Hub are not supported by the game's skin response system.

## OIW Add

What does OIW add, and how does it change skin behavior?

1. Environmental Factors: OIW introduces and defines: Atmospheric moisture (humidity) / Temperature / Wind / Dryness / Human perspiration.

2. Expanded Weather System: In addition to the four extreme weather types already present in the game, OIW introduces 12 additional weather conditions that can dynamically change during gameplay.

3. Ecology-to-Skin Simulation: OIW establishes environmental skin response rules based on real-world relationships between: Temperature and humidity / Wind speed and humidity / Combined thermal perception / Human sweat generation.

4. Ecosystem Anchor Point: The ecosystem is calibrated around: 22°C Temperature / 60% Humidity / 0 m/s Wind Speed. This state represents environmental equilibrium. Under these conditions, the environment and the human body are balanced, resulting in a stable skin state.

5. Ecology Phase Climate Profiles : Each ecology phase has its
