# Final Step Before packaging your project, all Building Blueprints should be converted into Final Blueprints. A Final Blueprint acts as an optimized container that consolidates one or more blueprints into a simplified and performance-optimized version. To perform the transformation, use the “Transform to Final” button (building should be selected) from the "Final & optimization" tab.

Or you can select the option from Scripted Actions.

If your map contains multiple buildings that need conversion, navigate to the Check Map tab. Click Check Blueprints to Fix:

Then use the Fix button under the Buildings section to begin the batch transformation:

The Max Iteration parameter determines how many blueprints can be converted to Final Prefab Blueprints in a single batch. To prevent system overload or freezing, avoid setting this value too high. For example, if Max Iteration is set to 50 and you have 300 Building Blueprints, you will need to click the Fix button six times until all are processed.
