It looks like Recap is pointing up correctly. I don’t think Recap is the problem, it is showing the coordinates correctly (with positive y-values, which is correct according to the location of the project) for the original .las file (this file comes straight from a lidar scanner). The y-values get a negative value when importing the *.las file into Unreal. I’ve also tried to import a .pts and .e57 file into Unreal, same result, negative y-values.
What to do now? I’m pretty sure the lidar files are correct.
edit I’ve converted the .las file to .txt. All y-values are positive, but when I import this .txt file into Unreal, all y-values are negative. What’s the place to report a bug for this plugin?
