Silhouette plug-in projects should not be copied and pasted within an OFX host because this workflow can cause stability and project integrity issues. Silhouette does not support copy/paste operations for plug-in projects in OFX environments.
Copy and paste limitations in Silhouette OFX workflows
Silhouette plug-in projects in OFX hosts may encounter problems when using copy and paste due to how project data and node structures are managed internally.
Issues that can occur include:
Project corruption or broken node connections
Loss of tracking, paint, or compositing data
Unexpected behavior or instability in the host application
Inconsistent results when reopening or rendering projects
Because of these limitations, copy/paste workflows are not reliable for Silhouette plug-in projects in OFX hosts.
