Hi, is there a tool to control strength of S_NOISE or ETA via mask/map? Need to reduce/increase S_NOISE for some parts of image. Of course, it can be done using mix of multiple ksamplers, but generation time become too high. for those who interesting about NOISE and ETA, here's some info about them |

@AlexD81 it's possible for i don't think masks with ETA would make sense, ETA doesn't directly control the noise level. it's more like where the step begins and ends (and then based on ETA noise might get added to adjust the level to where a step normally would end). so to do masking with ETA you'd have to step to different sigmas in the actual sampler. not exactly your question but if you want to have a lot of control over sampling you might also be interested in this project: https://github.com/blepping/comfyui_overly_complicated_sampling (OCS also has integration with ComfyUI-sonar, you can use all the custom noise types from Sonar with it.) |

@AlexD81 it's possible for
s_noise
(in a slightly roundabout way) with mySonarCompositeNoise
node. the example actually demonstrates using stronger noise in some areas based on a mask: https://github.com/blepping/ComfyUI-sonar/blob/main/docs/advanced_noise_nodes.md#sonarcompositenoisei don't think masks with ETA would make sense, ETA doesn't directly control the noise level. it's more like where the step begins and ends (and then based on ETA noise might get added to adjust the level to where a step normally would end). so to do masking with ETA you'd have to step to different sigmas in the actual sampler.
