Quick Shader is a utility that automates the standard node setup process for basic materials. Instead of manually adding and connecting nodes, the tool instantly generates a Principled BSDF setup using a single image texture. The script automatically routes the image into the base color, processes it through a color ramp for the roughness channel, and configures a bump node using the same image. It also applies common default values to the specular, bump height, and distance settings to streamline the initial material creation workflow.
