Video (loop) of the Sponza model by M.Dabrovic with some sculpts from ThreeDscan.com.
Path OCL PGI with OIDN (70%), 22h for 600 frames on RTX 2070 + GTX 1060.
The original materials don't do well in HD resolution. Maybe when we get a bevel node I will give it another go with better materials.
First time for me to use path and target tracking in Blender, doesn't work smoothly with motion blur at close inspection, there are some jerks where the motion blur pattern suddenly shifts.
