## Inputs

### Op

Parameter ID: `NET_MAXON_NEUTRON_OP_INPUT`

The use of this input is not mandatory, but it bears the advantage that you can directly define a position, size and rotation for the geometry. For this purpose you can, for example, connect another geometry here or simply use a *Matrix Op Node*. This is also interesting if you want to define the actual placement of the geometry only by a subsequent *Matrix Op*, because you then have a second reference, as is often helpful, for example, when using a *Null object* with objects in the *Object Manager*.

### Geometry

Parameter ID: `GEOMETRYIN`

Here you can connect the geometry from which a complete geometry should be created. This information is provided, for example, by many Nodes in the *Geometry Mesh group*.
