AAA Combat Prototyping Pipeline — Multi-Phase Ability Suite & System Architecture

Engine: Unity (Custom Pipeline / Unity Rendering Pipeline)

Tools: Custom ShaderGraph, Amplify, Advanced Velocity Curves, Maya, Animation Timelines

The Challenge
Design a magical, readable level-transition asset that visually cues player progression in an on-rails shooter. The effect must dynamically assemble on screen, support layered environmental particles, and provide a clear frame for the tech art team's central portal render texture.

Whatever it is, the way you tell your story online can make all the difference.

The Multi-Phase Sequence

  1. Activation: Opposing vine branches dynamically track and lock together to form a geometric perimeter.

  2. Ignition: Layered environmental smoke fills the frame while ambient firefly particles violently explode outward.

  3. Stabilization: Sustained emissive flow textures and panning distortion maps run across the meshes to signify an active travel threshold.

Technical Implementation & Toolset

  • Mesh & Path Animation:

    • Authored custom, detailed branch geometry using Maya.

    • Directed the meshes along separate, opposing semi-circular tracks to execute a top-to-bottom meeting that perfectly aligns into a circular frame.

  • Shader Architecture & Optimization:

    • Shared and adapted the custom Alpha Clip shader logic originally engineered for Crystalline Devastation to maintain stylistic project cohesion.

    • Implemented an advanced Blend Shading Pipeline (rather than simple additive rendering) to preserve dark color values, textures, and silhouettes against bright game backgrounds.

  • Dynamic Material Effects:

    • Integrated Flow Textures and Panning Distortion Maps to introduce non-uniform, shifting motion across the smoke and portal surfaces.

    • Embedded adjustable Emissive Channels to dial in high-contrast glow intensities suited for retro lighting aesthetics.

  • Particle Simulations:

    • Authored specialized smoke modules to anchor the portal structure to the environment.

    • Coded an outward-bursting particle system to scatter magical firefly elements upon portal completion.
