Hi @TonyJim
Let’s see…
Reduce Model Complexity: Try simplifying the assembly (e.g., remove parts or consolidate meshes) to reduce the load during the import.
Update Plugins and Engine: Ensure Datasmith plugins and Unreal Engine are up to date to avoid compatibility issues.
Monitor Resource Utilization: Monitor CPU and RAM usage to ensure Unreal is not slowing down from the complexity of the import.
Use Python Scripting: Transform individual parts to Blueprints with Python, potentially bypassing the freezing issue.
Review Logs: Check Unreal’s logs for error messages or crash dumps to identify the cause of the freeze.
Create Actor Manually: Rather than converting to a Blueprint, create a new Actor manually and add your Static Mesh components.
