 ### OIDN
 
 [Open Image Denoise](https://github.com/RenderKit/oidn) is a denoise library which uses machine learning techniques to reduce noise. To configure it, you must provide a URL to a weight file. One option is: [oidn-weights on GitHub.com](https://github.com/RenderKit/oidn-weights/blob/master/rt_hdr_alb_nrm.tza).
