Sage_EmptyLatentImagePassthrough
Empty Latent Passthrough
Creates an empty latent image and passes width/height for easier wiring. Includes a switch for SD3 compatibility.
Inputs
Required
- width (INT): The width of the latent images in pixels (default: 1024, range: 16 to MAX_RESOLUTION, step: 8)
- height (INT): The height of the latent images in pixels (default: 1024, range: 16 to MAX_RESOLUTION, step: 8)
- batch_size (INT): The number of latent images in the batch (default: 1, range: 1-4096)
- sd3 (BOOLEAN): Enable for SD3 compatibility - changes latent channels from 4 to 16 (default: False)
Outputs
- latent (LATENT): The empty latent image batch
- width (INT): Pass through the image width
- height (INT): Pass through the image height
Usage
Use to generate latent images and pass dimensions to downstream nodes. The passthrough outputs make it easier to wire width/height to other nodes without additional connections.
Notes
- Creates empty latent tensors on intermediate device for memory efficiency
- SD3 mode uses 16 channels instead of 4 for compatibility with SD3 models
- Latent dimensions are automatically scaled down by factor of 8 (standard for diffusion models)
- Width and height must be multiples of 8 for proper latent space alignment
- Batch size allows creating multiple latent images in a single tensor
- Useful for starting generation workflows with proper dimension tracking
