I am excited to present Extreme PBR Nexus, an addon that I have created with great enthusiasm to streamline the realm of 3D materials, a project that I have diligently enhanced over a span of 4 years. Extreme PBR is intended to alleviate the burden of dealing with Blender's nodes. I have crafted a user-friendly interface that greatly eases the handling of more than 1800 materials.
