Snoodler's SD 1.5 to SDXL 1.0 LoRa Workflow

Update 02/14/2024: I have release V2 of this workflow. It now comes with less spaghetti. Added a few custom nodes to help ease of use and keep things tidy. Added in FaceDetailer and UltimateSDUpscale. Also added in nodes for ControlNet implementation for trying to re-create older images.

About

This is a simple workflow that helps you use SD 1.5 LoRa's with the new SDXL 1.0 models. Render your old SD LoRa's in 1024x1024 the easy way!

Are you frustrated that you can't use your old SD 1.5 LoRa with the new SDXL 1.0 models? Look no further! This workflow helps you render an image using the new SDXL 1.0 models in a 1024x1024 size or larger, then use that rendered image as a baseline for your SD 1.5 models and LoRa to change. This not only enhances your pictures by using the new SDXL 1.0 models for better detail and generation, but now your old LoRa will be rendered higher than the old 512x512 size.

Now you can use all those old futanari LoRa's you have collecting dust with SDXL 1024x1024 renders! 🤣

Usage Tips

This workflow uses Efficiency Nodes and some Impact Pack nodes. I have included note nodes in each group within the workflow to help. I want to warn you that if you get strange images or they do not seem like they are rendering completely, it is most likely due to a VAE problem. I explain this inside the note nodes and it can be easily fixed by simply reloading the workflow.

Depending on the LoRa you are trying to use, you will have to think about how your base image should be generated and prompted. Most style LoRa do all the work by themselves. If you have a very niche LoRa for example a coffee latte style LoRa, it might take some creative prompting to get the base image that will let your SD 1.5 models and LoRa complete the correct work.

Thank You!

Thanks for checking out my workflow! Please leave a like and rating if you try it and like what you see. I'm fairly new to ComfyUI and this whole AI generation, but if you have any feedback or questions feel free to post them and I'll help in any way I can.
