Procedural Air And Surface Dust

by Blender Easy in Modifier Setups

These two procedural generators for Blender make it easy to add realistic dust to your scenes.
The first generator creates dust in the air, while the second generator creates dust on the surface of objects.
Both generators are highly customizable, so you can create the perfect dust effect for your scene.
These generators are perfect for artists of all skill levels, from beginners to professionals.

Air Dust

This unique tool allows you to quickly generate aerial dust particles.

Works pretty well with Depth of Field and gives you that extra realism to your shots.
As you are emitting from a mesh, you doesn't even need to simulate, just create a box in the area want the dust particles, and you are ready to render.
As it uses instances, you can use an insane amount of particles without using too much memory.
It also allows you to simplify how those particles is shown on the viewport, so you don't have a huge impact on the performance while working on the scene

You just need to Append the .Blend File to your scene, selecting the AirDust Inside the Nodetree folder.
Select a object to emit the particles and load the AirDust Geometry Node on the Modifiers tab.

Dust Gen

This tool allows allows you to quickly scatter a layer of geometry dust on the surface in a very realistic way. As it uses instances, you can scatter millions of dust instances without using too much memory.

This is far better them using just textures because it allows you to apply the effect to an entire collection and this is not resolution dependent, so you will get crisp renders even on low res models.
Using particles to do this will for sure make you waste a lot of time and even them you will not gonna have the same result.
You can go really crazy with this, because the tool has settings to show a lighter version on the viewport so you can work on this without having performance issues.
It comes with a control to determine lower the amount of instances on the viewport while keeping the full density at the render time.
You can mask a region to preview the full density in an area without exploding your pc while you are working and it has a checkbox that let you to show only basic points on the viewport, with also increases performance.

You can even use a roughness map to control this.

More Info;

To use this you just need to append the "DustGen" to your scene while selecting the "DUSTGEN" inside the "NodeTree" folder. Apply the transformations of the object and add the Geometry Node "DUSTGEN" modifier to your object.

You can follow the video above to see how to use this.
