OpticalPattern ControlNet engine for Sentinel StreamDiff

Prebuilt TensorRT engine that fuses the SDXL-Turbo UNet, the OpticalPattern ControlNet (Civitai 161132, v10e by nacholmo) and the SDXL IP-Adapter into the single UNet engine that Sentinel's StreamDiff node loads. It makes real-time optical illusions from a live camera at 896x512.

Code, the Sentinel project, the OP_Pattern control-image Module, build scripts and tuning notes: https://github.com/jhurlbut/sentinel-opticalpattern-controlnet

Files

File	Size	What
`profiles/sdxl/custom/opticalpattern/896x512/unet_controlnet_union_ipadapter_fp16.engine`	8.4 GB	The fused engine. Must keep this filename and folder layout inside Sentinel's `engines/`.
`demos/op_diffusion_cloud_face.mp4`	58 MB	Node output: a face illusion hidden in clouds
`demos/sentinel_window_spiral_interchange.mp4`	45 MB	Sentinel window: highway interchange bent into a spiral

Compatibility

This is a TensorRT plan, not portable weights. It only loads on the GPU architecture it was built for:

—NVIDIA RTX 50-series (Blackwell, sm120). Built on an RTX 5090 Laptop GPU.
—TensorRT 10.15.1 runtime, which is what Sentinel 0.5.66 ships as nvinfer_10.dll.
—Sentinel 0.5.66 or newer, engine_tier = ControlNet + IP-Adapter, FP16, 896x512.
—About 9 GB of VRAM for this engine plus Sentinel's CLIP, VAE and IP-Adapter engines.

Any other GPU generation or TensorRT version: rebuild with the scripts in the GitHub repo. The build takes 30 to 60 minutes.

Install

git clone https://github.com/jhurlbut/sentinel-opticalpattern-controlnet
python sentinel-opticalpattern-controlnet/export/install_custom_pack.py --name opticalpattern --controlnet --engine <downloaded .engine> --display "SDXL OpticalPattern CN 896x512"

Then open the Sentinel project from the repo, set the StreamDiff node's engine resolution to opticalpattern (896x512) and relaunch. Full steps and the measured tuning recipe are in the repo README.
