MDust is a Geometry Nodes setup that procedurally generates dust particles on object surfaces. It works by scattering particle instances from a user-defined collection onto target objects grouped within a specific target collection. The system automatically concentrates the particle scattering along the top world-normal of the objects, simulating how dust naturally settles.

Users can adjust the particle count, scale, and random seed directly from the modifier properties panel. The tool is designed to add fine detail and realism to macro renders, architectural visualization, and fabric materials.
