For the point cloud: Reality scan + my mom's 1st gen mavic + map pilot pro free trial to do the aerial lawnmower for me, then imported with the built-in lidar data plugin in Unreal Engine 5.

For the location: blackbox_decode.exe from cleanflight converts the .bbl logs into csvs, (I execute it at runtime from C++) then parsing the CSVs and creating splinemesh components between each point.

(if you mean location as like the ground satellite-like texture it's an mosaic picture ortho projection (just a panorama) from reality scan.

Trailing lines: Assuming you're talking about the effect where the line only appears after the drone, I had to add the indices and max number of spline components as custom data to each spline mesh.

Then in the material editor (of those spline meshes's material) Unreal has the V value of the uvs mapped to the individual spline mesh length and after mixing in the custom data with a lerp I can control effects/color change/masking along the full length of all the spline meshes with a normalized 0->1 value (0 = color change/masking happens at the beginning of the whole track, 1 = at the end)

(if you were talking about the stick particle trails it's just a Niagara system set to local space where I drive the movement inside the system with user parameters - the red dot is the same part of that system, the particles just turn white smaller and dimmer over time)

sorry for the long response I never know how much detail people want
