https://civitai.com/models/1484845?modelVersionId=1679607 The module already has VAE. Unless you have specific coloring requirements, it is recommended to use the VAE inside the module. Due to the unique nature of v-pred, I have created a dedicated section for v-pred. If you need use LoRA, it's better to use the v-pred LoRA to avoid potential problems. Recommended Parameters: Samplers: DDPM(suggest) > Euler > DDIM (⚠️ Other samplers will not work properly) DDPM CFG: 5.5 (around 5.5) Steps: 40 (around 40) Hi-res: Upscale 1.5x or higher, Denoising strength 0.15–0.45 Euler CFG: 4~7 Steps: 20~30 Hi-res: Upscale 1.5x or higher, Denoising strength 0.15–0.45 Resolution: Total area around 1024x1024. Best to choose from: 768x1344, 832x1216, 896x1152, 1024x1024, 1152x896, 1216x832, 1344x768 ComfyUI : https://huggingface.co/Laxhar/noobai-XL-Vpred-0.5/blob/main/comfy_ui_workflow_sample.png For Training v-pred LoRAs : https://civitai.com/articles/8723/vlora-or-how-to-train-a-lora-on-v-pred-sdxl-model Adetailer : https://github.com/Bing-su/adetailer
