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

Parameter	Data Type	Required	Range	Description
model	MODEL	Yes	-	The model to apply skip layer guidance to
double_layers	STRING	Yes	-	Comma-separated list of double block layer indices to skip (default: “7, 8, 9”)
single_layers	STRING	Yes	-	Comma-separated list of single block layer indices to skip (default: “7, 8, 9”)
start_percent	FLOAT	Yes	0.0 - 1.0	The starting percentage of the denoising process when skip layer guidance begins (default: 0.0)
end_percent	FLOAT	Yes	0.0 - 1.0	The ending percentage of the denoising process when skip layer guidance stops (default: 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.

Outputs
