Intel Open Image Denoise 2 (Apache-2.0) behind the CMake option DLU_OIDN (off): an installed OIDN is used when found, else Intel's release package (pinned by hash) is downloaded and its libraries copied next to the servers. A denoiser only removes noise that differs from pixel to pixel; the icons' occlusion comes from the bake, per vertex, which it leaves as it is (checked: white noise 0.17 -> 0.006 relative spread, per-vertex blocks unchanged). So with denoise=oidn a model's icon is drawn from model.noao.nif (its colors before the bake) with its occlusion traced per pixel of the supersampled image (denoise_samples rays, default 4, with the bake's distance and strength and the ray backend), box filtered and denoised at the icon's size, guided by the colors and normals. The model keeps its baked occlusion. Icons drawn again from stored files use the stored model.noao.nif the same way. OIDN works on a thread of its own; its time is charged to the job's thread (UgcThrottle::Charge), so the CPU budget and the recorded CPU time include it. Check: configure with -DDLU_OIDN=ON; UgcServer --make-model x.lxfml out oidn and compare its icon.png with one made with off; an OFF build leaves icons as they were.
