Blender Guru’s Andrew Price walks through how to add dust to your renders in Blender. Adding details such as dust and fingerprints can really add another level of realism to your work.

Here, Andrew shows how to use the model’s normals to isolate the parts where the dust will go. You are also able to apply dust using the Fresnel to detail how the dust will behave along the edges of the model. Finally, adding an image will complete the process.
