I play D&D on Roll20, so was looking at ways to generate borders for characters and came across this SD3.5M LoRA: https://civarchive.com/models/948412/vtt-token-rings-35
They mentioned this would work with SD3.5 Large and not need a LoRA so I figured I'd try the starting prompt with Flux, and it worked better than I hoped for. So no LoRAs needed, but you can use other LoRAs depending on what look you're going for.
An Ollama generate node builds the prompt, you just need to put your thematical elements in the Prompt box and it will build it for you. For example: "rich mahogany wood and an explosion of autumn leaves in red, gold and orange". They key part to this is the system prompt for the LLM that's taken from the example prompts from the SD3.5M Token LoRA page linked above. If your prefer to do the prompt manually make sure it starts with the following:
"a high detailed circular tokenframe on a white background with an empty white centre. Design of " You can change the shape from circular and I've tried square and hexagonal so far and both worked.
It has 3 stages, Flux a 1024 x 1024 gen. An upscale to 2000 x 20000 and then a second lower denoise pass with Flux. As well as the main image it saves a copy with the background removed and made transparent.
For the generation group, there are groups for PAG attention, DetailDaemon and Multiply Sigmas (Stateless). These have a bypass group switch next to them for enabling/disabling them. The 2nd pass group also has their own DetailDaemon and Multiply Sigmas (Stateless) groups which can be controlled through the same Fast group bypasser.
The DeepSeek node I use doesn't appear to be in ComfyUI Manager, but you can git clone them from here: https://github.com/comfyuiblog/deepseek_prompt_generator_comfyui
