🏷️ LoRA Loader Prompt Tags

Loads LoRA models using tags in the prompt. The basic syntax is . - The default strength is 1.0 if not specified (e.g., ). - A strength of 0 is treated as 1.0. - If an invalid strength is provided (e.g., non-numeric text), it will also be treated as 1.0. You can provide a separate weight for the CLIP model. - Syntax: - If the CLIP weight is omitted, it defaults to the model's weight. When you use a tag like , the node searches for the best matching LoRA file. If the name is not exact, it uses a scoring system to find the most likely candidate. Here is the order of priority: 1. Exact Match: An exact filename match (e.g., myLora.safetensors) is always preferred. 2. Numbered Versions: It intelligently handles numbered versions (e.g., myLora-1, myLora-2). If you ask for myLora-2, it will prioritize that file. If it can't find it, it will look for other numbered versions or the base myLora file. 3. Prefix Match: It will look for files that start with your requested name (e.g., myLoraAndMore.safetensors). 4. Contains Match: It will look for files that contain your requested name anywhere in the filename. 5. Path Priority: Files located closer to the root of your LoRA folders are given a slight priority boost over files in deep subdirectories. Route the model and clip through the node. Use the output [STRING] to have the prompt without the -tags.

💾 Save Image With Metadata

Save images with Civitai-compatible metadata auto-detected from your workflow. This node is integrated into this pack as an adapted copy of ChronoKnight's original node. Original source: - https://github.com/KChronoKnight/Chrono-Save-for-Civitai - images: Image batch to save. - filenameprefix: Supports strftime, %date:yyyy-MM-dd - hh.mm.ss%, plus %seed and %model. - folder: Output subfolder under ComfyUI output dir, supports strftime and %date:...%. - fileformat: png, jpeg, or webp. - quality: JPEG/WebP quality. - embedworkflow: Embed workflow metadata into saved image. - striploraprompt: Removes and embedding tags from prompt text in metadata output. - positiveoverride (optional): Override positive prompt text. - Captures prompt/negative prompt and LoRAs from executed runtime graph paths (sampler upstream), with graph parsing fallback. - Writes A1111-style parameters metadata. - Models used captures base model + LoRA

💾 Save Text File With Path

This node is adapted and enhanced from the Save Text File node found in the YMC GitHub ymc-node-suite-comfyui pack. The node can now give you a full file path output if you need it, as well as output the file-name as a separate output, in case you need it for something else. > [!IMPORTANT] > #### 2024-06-05 - Version 1.1.1 > The node was severely updated so existing workflows are going to break. I won't do another overhaul like this. > > The new node is more consistent in functionality and more intentional with the inputs and outputs. > > It now handles more edge cases and supports both a prefix, suffix, a dynamic counting with customizable separator before/after the counter in the right circumstances. > > Sorry for any troubles caused.

📅 Format Date Time

This node converts date and time formats into literal outputs for you to use. respectsystemlocale toggle functionality: This option allows you to choose between standard SI formats (when disabled) or system-specific locale formats (when enabled) for the %x and %c directives. - Disabled (Default): %x forces YYYY-MM-DD, and %c forces YYYY-MM-DD HH.MM.SS. providing consistent results across different systems. - Enabled: %x and %c use your operating system's locale settings, which may result in formats like MM/DD/YY. %%Y = %Y = Year %%m = %m = Month %%d = %d = Day %%H = %H = Hour %%S = %S = Second %%f = %f = Microsecond %%x = %x = Date (Affected by respectsystemlocale) %%X = %X = Time %%c = %c = Date + Time (Affected by respectsystemlocale) %%p = %p = am/pm %%A = %A = Weekday %%a = %a = Weekday short %%B = %B = Month %%b = %b = Month short %%j = %j = Day of year %%W = %W = Week index (Monday start) %%w = %w = Weekday index (Monday start) %%U = %U = Week index (Sunday start) %%u = %u = Weekday index (Sunday start) %%%% = %% = Prints a literal %%

📐 Resolution Image Size Selector

Creates resolutions and a latent from presets, user presets, or input images. Use the preset drop-down for some image generation standard resolutions. The presetuser input will be created on first launch, and you can edit the config for this in: ComfyUI/customnodes/ComfyUI-mnemic-nodes/nodes/resolutionselector/userresolution.json The custom width and height values are only used with the Custom preset. The multiply scale multiplies the final results and outputs them as multipliedwidth and multipliedheight. This is useful when it comes to figuring out a desired upscale resolution based on variable inputs. The swapwidthandheight option swaps the final width and height. The image input can be used. This has the highest priority. If it is used, we then take the image input width and height. imageminlength ensures that an input image size has at least this length on its shortest side. imagemaxlength ensures that an input image size has at most this length on its longest side. The snaptonearest ensures specific snapping on the final output value. This can be set to 8 or 16 for good divisible sizes, or any value that you need to work with. The batchsize option is used to create multiple output latents when you use tha latent output node.

🖼️📊 Metadata Extractor (List)

Extracts metadata from a list of images or a folder of images. The input images are loaded via a path. Either directly to an image file, or to a folder with multiple images. The metadata should work on both jpg and png images, and it will do what it can to extract from A1111/Forge/ComfyUI image metadata. > [!IMPORTANT] > To cycle through each input entry one by one in the list, you'll want to set the seed input to increment. > [!WARNING] > Be mindful of the maxfilecount setting when working with large folders. Loading a large number of images can consume a significant amount of memory and slow down your workflow. It is recommended to set a reasonable limit to avoid performance issues. Without a maxfilecount limit, things will take a long time to load each time and comfy will get super laggy if you load a folder with hundreds or thousands of images. Each will be loaded into memory at the same time. Use the Metadata Extractor (Single) if you only need one image at a time! - Inputs: - seed: An integer that sets the starting index for selecting image-metadata pairs. Use the increment option in workflow settings to cycle through pairs sequentially. - inputpath: A string specifying the path to a folder containing images or a single image file.

PromptPropertyExtractor

The Prompt Property Extractor node is a tool designed to parse a string (like a prompt) and extract various workflow properties such as model checkpoints, VAEs, LoRAs, sampler settings, and even generate latent tensors. It allows you to define a large part of your workflow within a single text block, making it a useful tool for randomizing more parts of your generations than just a wildcard. The node accepts a primary input string and a set of default values for all supported properties. If a property is found in the input string, it will override the default value. - inputstring: The main text string to parse for properties. - model, clip, vae: Default model, CLIP, and VAE to use if not specified in the string. - cfg, steps, sampler, etc.: Default values for all standard sampler and image properties. It is important to understand which model/CLIP/VAE is used when multiple sources are available (Input pins vs. Tags). Priority Order (Highest to Lowest): 1. Specific Tag: or always takes the highest priority. 2. Checkpoint Tag: If a tag is present: Model: Always loaded from the checkpoint. CLIP: Loaded from checkpoint IF loadclipfromcheckpoint is True. VAE: Loaded from checkpoint IF loadvaefromcheckpoint is True. 3. Input Pin: The model, clip, and vae inputs are used if they are not overridden by the above. Examples: loadclipfromcheckpoint = True + Input CLIP + tag: The Checkpoint's CLIP is used (Input is ignored). loadclipfromcheckpoint = False + Input CLIP + tag: The Input CLIP is used. loadclipfromcheckpoint = True + Input CLIP + (NO tag): The Input CLIP is used (Setting i…
