You only need to follow this guide if you are upgrading your UE4 version of Player Building System V2 to UE5.
Make a backup of your project before following this guide!
If you are creating a new Player Building System V2 project from the Epic launcher select the UE5 engine version when creating the project and the project will already have all the changes made in this guide!
Once you have opened your UE4 version of your Player Building System V2 project in UE5 follow the instructions below.
Start by downloading the files linked below, then unzip them and copy the video below.
Next open your project and make sure the files in the Chaos folder are there.
Next copy the video below, location at the top of the video.
Add the highlighted nodes shown in the image below, location at the top of the image.

Now you will need to go though each build part blueprint (which you can find in the Blueprints/BuildParts folder in the content browser) and assign the correct chaos mesh to the Geometry Collection component like the video below.
Note – You will need to do this for all the build part blueprints not just the ones shown in the videos, that is an example! Some build part blueprints will require extra steps, I have included videos for them below.
You do not need to do this for any of the Master Build Part blueprints.
Below are videos of the build part blueprints that require extra steps.
Next select the GeometryCollection component in the BP_MasterBuildPart and untick Visible, like the image below.

Next go to the M_Placement material and tick on the setting shown below.

Add the highlighted nodes shown in the image below, location at the top of the image.
