Hey, awesome human! If you’ve got an extra coffee lying around (or, you know, the cost of one), I’d love to turn it into creative fuel! ☕️ It’s like magic beans, but instead of a beanstalk, you get more cool content. Thanks for keeping me caffeinated and inspired!

Step 1: Define Your Batch Image Location

Choose your default location for batch image outputs when using ComfyUI. Example folder path:

D:\AI_GENRATION\ComfyUI_WORKING\ComfyUI\custom_nodes\ComfyUI-Inspire-Pack\prompts\cartoon\fluxbatch1.txt

#### Step 2: Text File Format for Prompts

Follow this exact format when creating your text file. The positive and negative prompts should be formatted as shown, with the correct number of minuses in between.

**Text Format Example:**

positive: A mysterious sorcerer, cloaked in dark robes, stands in a candlelit chamber filled with ancient scrolls and magical artifacts. His hands glow with swirling energy as he prepares a powerful spell, his face shrouded in shadow. The atmosphere is mystical and ominous. <lora:Cute_3d_Cartoon_Flux:0.7>  

negative:  

----------------

positive: A steampunk-inspired airship flying over a bustling Victorian city. The ship is adorned with brass gears and smokestacks, and the sky is filled with clouds and other flying vessels. The scene is full of adventure and mechanical wonder. <lora:Cute_3d_Cartoon_Flux:0.7>  

negative:  

----

positive: A cute, chubby dragon sits atop a pile of colorful, glowing gemstones in a cozy cave. Its scales shimmer in the light, and its wide eyes are filled with curiosity and mischief. The style is playful and whimsical, capturing the dragon’s endearing charm. <lora:Cute_3d_Cartoon_Flux:0.7>
