Hello @armada_studios,
can you please also share some print screen of your project? If I understand it correctly, there was also the issue with merging the components? In that case you need to have georeferenced data or you need to use the control points to merge the components. Automatic merging of laser data and images is quite rare, as it need a perfect data overlap.
As you are using the already aligned data, you should import the laser scan as Exact, Georeferenced, Local.
Can you also check the workflow mentioned in this post: Coordinates Coordinates Coordinates - #16 by OndrejTrhan?
Were you using just Lock pose for continue settings or also the Absolute pose was set as Locked?
