Glowing Mushrooms

A comparrisson between different Denoising methods, all denoised images are rendered with 128 samples.

4096 Sample render for comparrisson, of what an "optimal" render would look like.

SuperImageDenoiser (SID) having the best results
Intel Open Image Denoiser (OIDN) being very close
Nvidias OptiX Denoiser had more smearing than the other 2 AI denoisers.
Blenders Default Denoiser is based on an algorythm, instead of an AI, and struggles heavily with volumetrics.
