Mesh

In the Mesh module we will be able to convert our particles into geometry. We will have different options to generate a more detailed geometry, smoother, with Noise or work only with particles (for example to generate sand).

We will also be able to configure the Motionblur.

Remesh Settings

Here we can configure the main characteristics of our mesh.

Voxel Resolution: Indicates the resolution of our geometry, the lower the value, the higher the resolution.
Min/Max: The size of the geometry, to be able to adapt it as much as possible to the volume of the particles.
Smooth XYZ: A smoothing for our geometry, can be applied for each axis X,Y,Z separately.
Adaptivity: A decimate for our geometry and save some polygons.

Noise

In the Noise options you can add a Noise to your mesh. You can configure different values such as scale, strength, detail, Roughness, etc... You can also choose in which axis you want to work (X, Y, Z). In addition, there is an option called Noise + Velocity that uses the velocity attribute of our particles to generate a much more interesting Noise.

Let's see the difference between Noise and Noise + Velocity.

Normal" Noise by changing different parameters to see the results.

The problem with the normal Noise is that it is a static Noise, it is not dynamic, and when the fluid is in motion you can easily see how the Noise remains fixed. This can lead to undesired results.

Noise + Velocity has a completely different result. It uses the velocity vectors to generate a more localized and Dynamic noise, which follows the fluid and has a much more interesting result.

Grain Settings

Here we can display the particles as dots/spheres or any object we want. It is very useful to generate simulation of sand, or grains of coffee, rice, etc... You can change the size of the particles, the quantity, add rotation (in case of using other objects than spheres), etc... You can also use the "extra dots" tool to add extra density of particles in specific areas, very useful to generate wet sand effects or to add "lumps" in the geometry.

Another interesting option of the Grain mode is that we can add our own geometry as a visualization of the particles.

Of course, we can work with both processes at the same time, mesh + grain, for example to make a chocolate and use the dots to generate almonds, etc... Or to include internal spheres in the fluid with some emissive effect or as bubbles.
