Three stylized glowing rock materials built entirely with procedural shader nodes in Blender. The materials are consolidated into custom node groups, providing sliders to adjust parameters such as scale, rock distortion, variation, details, emission intensity, and bump strength. All three materials are variations generated from a single procedural setup by adjusting these custom values. The download includes the Blender file with the materials, a final render image, and the HDRI lighting used in the scene.
