.yld

YLD files (YLD = Cloth Dictionary) in GTA V define physics simulation for clothing and accessories. They contain data that allows items like coats, skirts, or scarves to react dynamically to forces like wind, gravity, and collisions.

Main functions

• Physics simulation: dynamic clothing movement
• Force reactions: wind, gravity, collision responses
• Model linking: associated with .ydd (Drawable) or .yft (Fragment) files that define visual appearance

Characteristics

• Binary format: not directly readable as text
• Simulation data: vertices, weights, stiffness, transforms
• Controllers: references to simulation controllers

Tools for editing

• ZModeler3D: can import and edit .yld files (requires linked .ydd file)
• Sollumz: import requires both .ydd.xml and .yld.xml exported together from CodeWalker RPF (linked files)
