Autopsy Simulator
Advanced pathology simulation with realistic cadaver systems and forensic examination mechanics
Our Role in Autopsy Simulator
Yarrawah Interactive provided asset production for the Autopsy Only Mode in Autopsy Simulator, a detailed forensic simulation game. Our work focused on retexturing and improving cadaver models with dynamic injury visualization, procedural wound blending, and advanced shader networks. We enhanced four cadaver models through topology refinement, detailed re-sculpting, improved UV mapping and baking, and blendshape creation, delivering comprehensive material systems supporting unlimited injury variations and procedural detail.

Master Material Architecture
The material system consists of two primary components working together to enable dynamic wound visualization:
- M_Skin_Blend - Master shader controlling base textures and layer composition
- SG_WoundBlend - Subgraph handling multi-layer blending logic for up to 4 independent wound layers
Texture Array System
To overcome Unity's 16 texture sampler limitation while supporting 4 wound layers, we implemented a runtime texture array generation system. Each character material set requires 3 texture arrays:
- BaseColor Array - RGBA color variations for wound states
- Normal Map Array - RGB tangent space normals for surface detail
- Mask Array - Single-channel masks controlling blend regions
OldMan character: 9 texture arrays (3 material sets) | Samantha character: 12 texture arrays (4 material sets)
Layer Blending System
Each of the 4 wound layers supports independent control through RGBA vector parameters:
- Mask Intensity - Controls blend strength per layer
- Normal Intensity - Adjusts surface detail prominence
- Saturation - Per-layer color saturation control
- Hue Shift - Independent color shifting in degrees
- Power - Contrast and falloff control affecting blend sharpness
- Divide - Division values for fine-tuning blends (supports negative values for inversion)
- Global Intensity - Master strength control per layer
Performance Optimization
The system employs several optimization strategies:
- Runtime texture array generation for memory efficiency
- Single subgraph reused across all wound layers
- Texture array approach stays under Unity's sampler limit while supporting complex layering
- Procedural blending reduces need for unique texture sets
