Unreal Engine – Infinity Weather

Displacement:

• configurable displacement capture blueprint
• top-down projection of displacements rendered using shape definition in the shader (sphere, capsule, box, cylinder, decal, trace-sphere)
• skeletal mesh displacement supports
• interface for easy integration with all types of actors
• area of displacement move dynamically with the actor or camera
• time-based accumulation of snow
• displacements can be used for multiple other effects (like grass interaction)
• displacement material functions ( snow, mud, sand, grass)
• small world texture (1024×1024) can handle even 150x150m area

---

Post-process:

• two materials with fast dynamic switching between material permutations
• post-process effects (raindrops, frozen, sharpen/blur)
• pre-translucent effects (rain circles, heat haze, experimental glitter)
• reacts dynamically on weather conditions
• supports character and sequencer camera

---

Footstep:

• notify based footsteps detection system
• example footstep types (SFX, VFX) snow, rain, mud
• physics material support
• configurable footstep component adjustable per character
• footstep volumes with priorities and conditional spawning

---

Precipitation:

• defined effects snow, rain, dust, hail
• GPU friendly and efficient, implemented on single material and mesh.
• up to 65000 particles per emitter with high performance
• occlusion maps
• crossfade wind and rain sound effects
• Technical Details

---

Landscape:

• basic example materials (snow, mud, sand)
• advanced landscape material prepared for mixing displacement and dynamic weather.
• virtual texturing and layered landscape materials.
• multiple example ground layers (rock, grass, mud, sand)

---

Environment:

• weather controller actor
• spherical volumetric fog area and atmosphere and temperature
• weather surface material function (snow/wet layer)
• spline-based rainbow mesh with camera facing,
• water puddle decal
• directional light clouds shadow reacts on wind direction.
• wind reactive effects like precipitation, ground dust, flag, trees, bushes, grass, emitters
• example maps: Snow, Sand, Rain, World
• character reaction to strong wind
