ComfyUI Node: TextureViewer

TextureViewer:

The TextureViewer node is designed to help you visualize and manage various texture maps used in 3D rendering and digital art. This node allows you to input different types of texture maps such as color, displacement, normal, ambient occlusion (AO), metalness, roughness, and alpha maps. It processes these maps and converts them into a format that can be easily viewed and manipulated. The primary benefit of using the TextureViewer is its ability to handle multiple texture maps simultaneously, providing a comprehensive view of how these maps interact and affect the final rendered image. This node is particularly useful for artists who need to fine-tune textures and ensure that all maps are correctly aligned and functioning as intended.

TextureViewer Input Parameters:

color_map

The color_map parameter allows you to input an image that represents the color texture of your 3D model. This map defines the base colors of the surface and is essential for giving your model its overall appearance. The input should be an image file, and it is optional.

displacement_map

The displacement_map parameter accepts an image that represents the displacement texture. This map is used to create the illusion of depth and detail on the surface of your model by displacing vertices based on the grayscale values in the image. The input should be an image file, and it is optional.

normal_map

The normal_map parameter allows you to input an image that represents the normal texture. This map is used to simulate small surface details and lighting effects without adding extra geometry. The input should be an image file, and it is optional.

ao_map

The ao_map parameter accepts an image that represents the ambient occlusion texture. This map is used to simulate the soft shadows that occur in the crevices and corners of your model, enhancing the realism of the lighting. The input should be an image file, and it is optional.

metalness_map

The metalness_map parameter allows you to input an image that represents the metalness texture. This map defines which parts of the surface are metallic and which are not, affecting how the surface reflects light. The input should be an image file, and it is optional.

roughness_map

The roughness_map parameter accepts an image that represents the roughness texture. This map defines how rough or smooth the surface of your model is, affecting the way light scatters across it. The input should be an image file, and it is optional.

alpha_map

The alpha_map parameter allows you to input an image that represents the alpha texture. This map defines the transparency of different parts of the surface, allowing you to create effects like holes or partially transparent areas. The input should be an image file, and it is optional.

TextureViewer Output Parameters:

ui

The ui output parameter provides a dictionary containing the processed texture maps. Each key in the dictionary corresponds to a type of texture map (e.g., color, displacement, normal) and holds the processed image data. This output is essential for visualizing the texture maps and ensuring they are correctly processed and aligned.

TextureViewer Usage Tips:

• Ensure that all input texture maps are correctly aligned and of the same resolution to avoid inconsistencies in the final rendered image.
• Use high-quality images for your texture maps to achieve the best visual results.
• Experiment with different combinations of texture maps to see how they interact and affect the overall appearance of your model.

TextureViewer Common Errors and Solutions:

"Input image is None"

• Explanation: This error occurs when one of the input texture maps is not provided or is invalid.
• Solution: Ensure that all input texture maps are valid image files and are correctly loaded into the node.

"Failed to process texture map"

• Explanation: This error occurs when there is an issue with processing one of the texture maps.
• Solution: Check the format and resolution of the input texture maps. Ensure they are compatible with the node's requirements.

"Output directory not found"

• Explanation: This error occurs when the specified output directory for saving processed images does not exist.
• Solution: Verify that the output directory path is correct and that the directory exists. Create the directory if necessary.
