SDXL Workflow for Pixel Art Game Assets
fish_builds_daily · reddit · 2026-07-12
The author shares a ComfyUI workflow for generating 2D game assets using SDXL + a pixel art LoRA. It relies entirely on native nodes—just import the JSON to run it, no custom nodes required.
Configuration Details
- Base model: SDXL base
- LoRAs: pixel-art-xl (0.8) + smol-animals sdxl (0.6)
- Two generation branches:
- Creatures: 1024×1024, 25 steps, CFG 7, Euler ancestral
- Items: 512×512, 30 steps, CFG 7.5, standard Euler
Testing & Pitfalls
- The same set of negative prompts works for both branches: blur, low quality, watermark, text, signature, jpeg artifacts, bad anatomy, distorted.
- When generating item icons, even if prompted for a "transparent background," SDXL might still draw a scene behind it. The author found that adding "isolated on plain white background" makes it much easier to obtain a clean, cuttable white-background image.
- A quirk of the pixel art LoRA: it excels at a "blocky aesthetic" but tends to soften small details, such as a sword's crossguard.
The author concludes by asking if anyone knows of a pixel art LoRA that better preserves details at small icon sizes.
