This is a procedural sci-fi fan and air vent material built using Blender's procedural nodes. The material is packaged in a custom node group, allowing users to control various parameters to achieve their desired look.

The material settings include controls for the scale, the number of blades, rotation, and color. Additionally, the scale of the bolts, roughness, and bump intensity can be adjusted. The product includes the procedural material in a Blender file, along with HDRI lighting for testing.
