These files are ready for the LocalImageGen Unity asset. Use its model manager to download them; do not rename files or folders.

Converted with Unity 6000.5.5f1 and Unity Inference Engine 2.6.1. The customer-facing asset does not contain model weights.

Source and validation

• Upstream: stabilityai/stable-diffusion-xl-refiner-1.0
• Pinned upstream revision: 5d4cfe854c9a9a87939ff3653551c2b3c99a4356
• Validation: SDXL Base + Refiner at 512x512 and 768x768 under Unity D3D11; clean four/five-step low-noise handoff with no artifacts.

The Refiner UNet was re-exported locally from the official Stability AI checkpoint as unfused ONNX opset 14 before FP16 conversion. This avoids the incorrect low-noise predictions produced by the earlier third-party ONNX export.
