# Dev Log: Playing around with Comfy UI

Based on our recent [pivot](https://blog.sprited.app/pivot-descoping-machisoup-and-pixeltinker), I’m working toward the [SpriteDX](https://blog.sprited.app/wip-plan-for-spritex-prototype) prototype.

During my vacation, I’ve been doing some preliminary research on using **Flux pipelines** to build an image-to-image system for generating consistent retro-style pixel sprite sheets.

Here’s what I’ve explored so far:

* [Using Retro Pixel Flux LoRA for Pixel Art](https://blog.sprited.app/lora-prithivmlmodsretro-pixel-flux-lora)
    
* [Using Tile Control Net on Flux to lay out sprite sheet](https://blog.sprited.app/flux1-control-net)
    
* [Using Flux Fill Model for sprite sheet population](https://blog.sprited.app/flux1-fill-dev-for-sprite-sheets)
    

**TL;DR**: The `Flux1-Pro/Dev` model, when combined with **Retro Pixel LoRA** and **Tile ControlNet**, *can* generate consistent character sheets through image-to-image workflows.

But… it falls short when it comes to animation-ready sprite-sheets. I think the root issue is this: the models were trained on image types you’d find on Instagram or Pinterest—images optimized for *human* aesthetics, not machine-readable character animation. These reference styles just aren’t structured enough for animating frame-by-frame sprites.

So, I’m experimenting with using walk cycle templates sprite sheets as ControlNet input to guide the layout better. I’m not overly optimistic, but I want to test it out before ruling it out.

Today, I installed **ComfyUI** and started playing around with the Flux1-Dev models inside it. Mostly just prompt tweaking for now—nothing groundbreaking to share yet.

Tomorrow, I plan to plug in **IP Adapters** and **LoRAs** (as described [here](https://blog.sprited.app/pixel-post-levelup-your-pixel-art-walkcycle-animation-with-flux-ipadapter-v2-and-controlnet-2025-guide)) to try generating sprite sheets with walk cycles that follow a provided template. Fingers crossed.
