If you see a LoRA/Lycoris with a version lower than V8, it is eligible for an upgrade. Feel free to request an upgrade for an existing LoRA/Lycoris.
SDXL LoRA/LyCORIS works best on its original training model. You may need to reduce weight when using it with other models or additional LoRAs.
LyCORIS Combination Recommendation: Try using four of my LyCORIS models with the following weights: 0.4, 0.3, 0.2, 0.2 (or any combination with a total weight around 1.0).
