Draw Things for ComfyUI

Draw Things for ComfyUI is a bridge between ComfyUI and Draw Things via gRPC. It allows ComfyUI to build and send image generation requests to Draw Things - giving you more control over inputs and settings than Draw Things alone offers, and bringing the Draw Things sampler into your ComfyUI workflows.
