### Before we start...

Some people have complex, rich, layered backgrounds.
This LoRA said: "nah, just gray."
Honestly, the most emotionally stable thing I've ever trained.

## Tips

- Start with LoRA weight around **0.7** and adjust up/down depending on how strong you want the effect.
- Combine with other IDK_ LoRAs from this series for layered results (e.g. body + hair + style).
- Works with both realistic and stylized SDXL checkpoints.
- Use the trigger words in your prompt for best activation.
- If the effect is too subtle, increase weight or repeat the trigger word.
- If the effect is too strong / distorted, lower the weight to 0.5-0.6.

## Part of the IDK Series

This LoRA is part of the **IDK LoRA collection** — a set of specialized SDXL LoRAs that can be used individually or merged together. The merged version (**IDK.safetensors**) combines all of them using hierarchical semantic merging for maximum quality.
