ComfyUI Node: SDXL Quick Empty Latent (WLSH)

SDXL Quick Empty Latent (WLSH):

The SDXL Quick Empty Latent (WLSH) node is designed to quickly generate an empty latent space for AI art generation, specifically tailored for the SDXL model. This node allows you to create a latent tensor with predefined resolutions and orientations, making it easier to set up the initial conditions for your AI art projects. By providing a selection of common resolutions and the ability to switch between landscape and portrait orientations, this node simplifies the process of preparing the latent space, ensuring that you can focus more on the creative aspects of your work. The primary goal of this node is to streamline the setup process, offering a quick and efficient way to generate the necessary latent space for your AI art endeavors.

SDXL Quick Empty Latent (WLSH) Input Parameters:

resolution

This parameter allows you to select the resolution of the latent space. The available options are predefined resolutions that are commonly used in AI art generation. The choices include "1024x1024|1:1", "1152x896|9:7", "1216x832|19:13", "1344x768|7:4", and "1536x640|12:5". Each option specifies the width and height in pixels, followed by the aspect ratio. Selecting the appropriate resolution is crucial as it determines the dimensions of the generated latent space.

direction

This parameter lets you choose the orientation of the latent space. The available options are "landscape" and "portrait". Selecting "landscape" will maintain the width and height as specified in the resolution, while choosing "portrait" will swap the width and height values. This flexibility allows you to generate latent spaces that fit different artistic compositions and styles.

batch_size

This parameter specifies the number of latent spaces to generate in a single batch. The default value is 1, with a minimum of 1 and a maximum of 64. Adjusting the batch size can be useful when you need to generate multiple latent spaces simultaneously, which can save time and computational resources.

SDXL Quick Empty Latent (WLSH) Output Parameters:

latent

This output parameter is the generated latent space tensor. It is a multi-dimensional array filled with zeros, representing an empty latent space that can be used as the starting point for AI art generation. The latent tensor's dimensions are determined by the selected resolution and orientation, adjusted to fit the requirements of the SDXL model.

width

This output parameter indicates the width of the generated latent space in pixels. It reflects the adjusted width based on the selected resolution and orientation, ensuring that the latent space dimensions are compatible with the SDXL model.

height

This output parameter indicates the height of the generated latent space in pixels. Similar to the width parameter, it reflects the adjusted height based on the selected resolution and orientation, ensuring compatibility with the SDXL model.

SDXL Quick Empty Latent (WLSH) Usage Tips:

• Select a resolution that matches the desired output size of your AI art project to ensure optimal results.
• Use the direction parameter to quickly switch between landscape and portrait orientations, depending on your artistic needs.
• Adjust the batch size to generate multiple latent spaces at once, which can be useful for batch processing or experimenting with different initial conditions.

SDXL Quick Empty Latent (WLSH) Common Errors and Solutions:

Invalid resolution format
