ComfyUI Node: Match Texture Aspect Ratio

Match Texture Aspect Ratio:

The Object_MatchTextureAspectRatio node is designed to adjust the dimensions of a 3D object in Blender to match the aspect ratio of a given texture image. This node is particularly useful when you need to ensure that the texture applied to a 3D object is not distorted and maintains its original proportions. By scaling the object based on the texture's width and height, this node helps in achieving a more accurate and visually appealing texture mapping. This can be especially beneficial in scenarios where precise texture alignment is crucial, such as in creating realistic models or detailed visualizations.

Match Texture Aspect Ratio Input Parameters:

image

The image parameter expects an image input that will be used to determine the aspect ratio. This image is typically a texture that you want to apply to a 3D object. The node reads the dimensions of this image to calculate the appropriate scaling factors for the object. The image should be in a format that Blender can interpret, such as PNG or JPEG.

scale

The scale parameter is a floating-point value that determines the scaling factor applied to the object's dimensions. By default, this value is set to 0.001, which means the object's size will be adjusted to a very small scale relative to the image dimensions. You can adjust this value to control the overall size of the object while maintaining the correct aspect ratio. The parameter accepts values with a minimum step of 0.001, allowing for fine-tuned adjustments.

Match Texture Aspect Ratio Output Parameters:

This node does not explicitly define output parameters in the provided context. However, the primary outcome of using this node is the transformation of the 3D object's dimensions to match the aspect ratio of the input texture image.

Match Texture Aspect Ratio Usage Tips:

• Ensure that the image input is correctly loaded and accessible in Blender to avoid errors during processing.
• Adjust the scale parameter to achieve the desired size of the 3D object while maintaining the correct aspect ratio. A smaller scale value will result in a smaller object, and vice versa.
• Use this node in combination with texture assignment nodes to ensure that the texture is correctly applied to the resized object.

Match Texture Aspect Ratio Common Errors and Solutions:

Image not found

• Explanation: The specified image could not be found or loaded in Blender.
• Solution: Verify that the image file path is correct and that the image is accessible in Blender. Ensure that the image is in a supported format.

Object not selected

• Explanation: No object is selected in Blender for the transformation to be applied.
• Solution: Make sure to select the 3D object you want to resize before executing the node.

Invalid scale value

• Explanation: The scale value provided is not within the acceptable range or format.
• Solution: Ensure that the scale value is a floating-point number and within the acceptable range. Adjust the value to be a positive number with a minimum step of 0.001.
