modelVersions.description: <p>I found an <a target="_blank" rel="ugc" href="https://wandb.ai/johnowhitaker/multires_noise/reports/Multi-Resolution-Noise-for-Diffusion-Model-Training--VmlldzozNjYyOTU2">article </a>of @<a target="_blank" rel="ugc" href="https://twitter.com/johnowhitaker">johnowhitaker</a> for another noise offset method called "pyramid noise" - gave it a shot. It's very subtle and starts to kick in at a weighting at 2-3, because i had a settings error, so the outcome wasn't as i thought it was. At least the bleeding on high weights are now almost gone, therefore its loses much saturation i guess. Just play around.<br /><br /><em>If u use Additional Networks u have to push the Max Limit in the config file over 2 to get more depth.</em></p>
