+
+A script to convert LoRA models to ComfyUI-compatible format. ComfyUI does not directly support sd-scripts format Qwen3 LoRA, so conversion is necessary (conversion may not be needed for DiT-only LoRA). You can convert from the sd-scripts format to ComfyUI format with:
+
+```bash
+python networks/convert_anima_lora_to_comfy.py path/to/source.safetensors path/to/destination.safetensors
+```
+
+Using the `--reverse` option allows conversion in the opposite direction (ComfyUI format to sd-scripts format). However, reverse conversion is only possible for LoRAs converted by this script. LoRAs created with other training tools cannot be converted.

+
+LoRAモデルをComfyUI互換形式に変換するスクリプト。ComfyUIがsd-scripts形式のQwen3 LoRAを直接サポートしていないため、変換が必要です（DiTのみのLoRAの場合は変換不要のようです）。sd-scripts形式からComfyUI形式への変換は以下のコマンドで行います：
+
+```bash
+python networks/convert_anima_lora_to_comfy.py path/to/source.safetensors path/to/destination.safetensors
+```
+
+`--reverse`オプションを付けると、逆変換（ComfyUI形式からsd-scripts形式）も可能です。ただし、逆変換ができるのはこのスクリプトで変換したLoRAに限ります。他の学習ツールで作成したLoRAは変換できません。
