Simple version of the SkipLayerGuidanceDiT node that only modifies the unconditional pass during the denoising process. This node applies skip layer guidance to specific transformer layers in DiT (Diffusion Transformer) models by selectively skipping certain layers during the unconditional pass based on specified timing and layer parameters.

Inputs

ParameterDescriptionData TypeRequiredRange
modelThe model to apply skip layer guidance toMODELYes-
double_layersComma-separated list of double block layer indices to skip (default: “7, 8, 9”)STRINGNo-
single_layersComma-separated list of single block layer indices to skip (default: “7, 8, 9”)STRINGNo-
start_percentThe starting percentage of the denoising process when skip layer guidance begins (default: 0.0)FLOATNo0.0 - 1.0
end_percentThe ending percentage of the denoising process when skip layer guidance stops (default: 1.0)FLOATNo0.0 - 1.0
Note: Skip layer guidance is only applied when both double_layers and single_layers contain valid layer indices. If both are empty, the node returns the original model unchanged. The skip layer guidance is active only when the current denoising step’s sigma value falls between start_percent and end_percent (converted to sigma values internally).
