This SOP determines if connected faces have become separated. It stores the result as an attribute or deletes connected/disconnected faces.
Resolving issues with glass fracturing
A common issue with glass fracturing occurs when you have interior faces with detail in pieces of glass that haven’t broken apart. This can cause problems in rendering, since it’s a transparent surface. To resolve these types of issues, you can apply a RBD Connected Faces SOP after fracturing. This node will record the primitive number and distance to the opposite face on the inside faces of the fractured geometry. You can then use this information to decide whether or not to dissolve any interior faces on pieces that haven’t broken apart by using the Delete Connected mode on the RBD Disconnected Faces SOP.
The attribute type the connected primitive number and distance are stored as.
The name of the attribute storing the connected primitive number.
The name of the attribute storing the distance between primitive centers.
Distance threshold beyond which 2 connected faces are determined to have separated.
Stores the disconnected state as a primitive attribute.
Deletes connected faces.
Deletes disconnected faces.
The name of the attribute to store the disconnected state of the primitives.
