It is possible to shift the starting point of the cached rigid simulation.
Offset
This parameter is only relevant if your simulation is in → "Cache" mode. With "Offset" you are able to specify an individual frame offset for every fluid, rigid, elastic, or mesh node. This way it is possible to synchronize simulations with other animated Cinema 4D scene elements. Alternatively you can also define a global → "Frame Offset", valid for all simulation nodes. The global "Frame Offset" also affects the individual node offsets:
Total offset = frame offset + node-specific offset
Output Name
By default the name of the output file is same as the node name. You can use another name unchecking "Auto" checkbox and editing this field. This can be also useful to avoid collisions between nodes with the same name.
Enable
This node will be cached only if this option is checked.
