mDust is a geometry nodes setup that allows the user to generate dust particles on objects surfaces. Usable applications would be for macro/closeup renders, an extra dimension of realism for architecture renders, extra fuzz on fabric or just a regular old dusty floor. 

The setup is quite simple, it scatters particle instances from a collection onto objects located in a "dustyObjects" collection and concentrates the scattering to the top world-normal of the objects. 

The controllers you get in the modifiers tab are particleCount, particleScale and seed, as well as the ability to select the collections you want to use.

Have fun!

Update 1.1

Bug-fixes

This update adjusts the scale of the setup. There was some confusion as to why the dust where not visible for some users in some cases, and it had to do with the scale of the dust compared to the scene of the user, so now the dust is adjusted and scaled up for visibility and ease.

Now you can also more easily append the "mDust" collection into any scene from the demo-file and just replace the objects within the "dustyObjects" collection with your own objects!
