Summary

InZoi would benefit from an upgrade to Unreal Engine 5.7 and the integration of multiple advanced UE5 rendering, lighting, physics, and animation systems.
This enhancement aims to modernize performance, graphics quality, scalability, and modding potential.

Description

The current engine setup can be improved through several UE5.7-based technologies. These upgrades would provide stability, higher fidelity, better streaming, advanced lighting, and more realistic character animation.

This ticket outlines a combined engine modernization request.

Proposed Improvements

1. Engine Update

  • Upgrade project to Unreal Engine 5.7

  • Benefits: improved stability, new animation tools, better world streaming, updated editor systems

2. Rendering Enhancements

2.1 RTX Mega Geometry – Full Integration

Apply RTX Mega Geometry to:

  • full environment (buildings, terrain, vegetation, props)

  • all in-game objects

  • clothing & outfit meshes

  • Zoi character models

2.2 Nanite Foliage

  • High-density vegetation without LOD transitions

  • Efficient streaming for parks and outdoor areas

2.3 MegaLights

  • Scalable, accurate global lighting

  • Improved shadow precision

  • Enhanced night and interior lighting

2.4 Lumen GI & Lumen Reflections

  • Dynamic global illumination

  • Realistic reflections on glass, metals, water

  • Smooth indoor/outdoor transition handling

2.5 Ray Tracing Enhancements (Optional)

  • RT Shadows

  • RT GI

  • RT Reflections

  • RT Translucency

2.6 TSR 3.0

  • Sharper image quality

  • Increased performance

  • Better stability in large city scenes

3. World & Simulation Systems

3.1 World Partition 2.0

  • Improved large-world streaming

  • Better handling of dense urban areas

3.2 Niagara VFX Improvements

  • Enhanced weather (rain, fog, snow, wind)

  • Better smoke, dust, and environment particles

3.3 Chaos Physics & Chaos Cloth

  • More realistic object physics

  • Advanced clothing simulation for outfits and fabric types

4. Character Animation Systems

4.1 Motion Matching

  • More natural transitions between movement states

  • Smoother locomotion behavior

4.2 Full-Body IK / Foot IK

  • Better adaptation to slopes, stairs, uneven ground

  • More precise foot placement

4.3 UE5 Dynamic Animation System (High-Heel Support)

  • Automatic foot/leg adjustments based on heel height

  • Automatic hip/torso correction

  • No need for manual animation variants

  • Better modding support for footwear

Expected Outcome

Implementing these features would:

  • Modernize the engine

  • Improve visual fidelity

  • Increase performance in large city environments

  • Enhance character realism

  • Strengthen long-term scalability and modding support
