## Outputs

As of Cinema 4D 2025.1, it is also possible to attach custom properties to the particles, which can then be queried again in *Conditions*, in *Math* or *Data Mapper* modifiers, for example, or offset against other properties of the particles. The *Blend Modifier* offers a property for storage here.

To activate the corresponding storage, activate the option to the right of its name. A new custom property whose data type is compatible with the output value is automatically created and entered. These automatically generated custom properties are stored within the *Scene Settingss* and their *Particle Simulation* settings are listed in the group for *Automatic Custom Properties*.\
However, you can also use the group for *Manual Custom Properties* to create new properties by yourself. You will find an arrow button behind the respective name field of the *Output* properties, which can be used to open a selection list of the available custom properties. These lists are automatically filtered to display only the custom properties of the simulation scene whose data types are compatible with the *Output* value.

You can find out more about the manual creation of custom properties for saving and processing particle properties in the section on [Particle Simulation Settings](https://help.maxon.net/c4d/en-us/Content/html/OPBDSCENE-PBDSCENE_FP_GROUP.html.md) within the *Scene Settings*.

When using the following output, please note that the setting for **Neighbour Search** is also evaluated for its determination. In simulations with a large number of particles, an incorrect **Neighbour  Count** may therefore be output in the *Fixed* or *Dynamic* modes if too low a value is used for **Maximum Checks**.

### Neighbour Count

Parameter ID: `FP_BLEND_OBJECT_OUTPUT_NEIGHBOURCOUNT`

This integer value specifies the number of neighboring particles that are located within the **Radius** defined in the *Object* settings. Activating the **Neighbour Count** option automatically creates a custom property with a suitable *Integer* data type. Alternatively, you can click on the arrow button next to the name field to select one of your manually created custom properties that also uses this data type.
