Edge Fusion (URP) · Troubleshooting & FAQ

Edge Fusion's performance depends primarily on sample count and scene complexity. Use these guidelines to find the best quality/performance balance for your target platform.

Key Optimisation Levers

Setting	Recommendation
Sample Count	Use the quality preset dropdown for quick configuration, then fine-tune. Keep as low as possible while maintaining acceptable visual quality.
Binary Search Steps	Reduce alongside Sample Count for faster edge location.
Early Exit Hits	Lower values improve performance, especially with jitter enabled. The default of 5 is usually sufficient.
Max Blend Distance	Set a reasonable limit to avoid wasting GPU time on distant pixels that are too small to benefit from blending.
Blend Layers	Only include objects whose edges should blend. Exclude transparent, particle, FX, and UI layers. The default "Everything" should be narrowed to "Default" or specific layers.
Jitter	Jitter breaks GPU cache locality. When using jitter, keep sample count lower. Disable entirely if performance is critical and TAA smoothing is not needed.
Intra-Object Fusion	The most GPU-intensive option. When enabled, it adds per-pixel normal reconstruction to the ObjectID pass, fill pass, and blend pass, and forces a larger texture format (RGBA32F instead of RG32F), doubling bandwidth. Keep it disabled unless you specifically need edge blending within a single mesh. If enabled, use Per-Object mode to limit the cost to only the meshes that need it.
Noise	Adds a 3D texture sample per detected edge. The cost is minor on desktop but can add up on mobile. Set Noise Intensity to 0 if you do not need organic-looking edge variation.

Platform Guidelines

Platform	Suggested Sample Count	Notes
Mobile	4–8	Disable jitter; set a conservative Max Blend Distance
Console	12–20	Enable jitter with TAA for best quality
PC (mid-range)	16–24	Good balance with moderate jitter
PC (high-end)	24–32	Full quality with jitter and TAA
