The StableCascade_EmptyLatentImage node creates empty latent tensors for Stable Cascade models. It generates two separate latent representations - one for stage C and another for stage B - with appropriate dimensions based on the input resolution and compression settings. This node provides the starting point for the Stable Cascade generation pipeline.

Inputs

Parameter	Data Type	Required	Range	Description
width	INT	Yes	256 to MAX_RESOLUTION	The width of the output image in pixels (default: 1024, step: 8)
height	INT	Yes	256 to MAX_RESOLUTION	The height of the output image in pixels (default: 1024, step: 8)
compression	INT	Yes	4 to 128	The compression factor that determines the latent dimensions for stage C (default: 42, step: 1)
batch_size	INT	No	1 to 4096	The number of latent samples to generate in a batch (default: 1)

Outputs

Output Name	Data Type	Description
stage_c	LATENT	The stage C latent tensor with dimensions [batch_size, 16, height//compression, width//compression]
stage_b	LATENT	The stage B latent tensor with dimensions [batch_size, 4, height//4, width//4]
