Ok, I've followed your suggestions but I was not lucky. This is the the procedure I've followed, I hope you might help me to find a solution:
1) Opened Unregistred LAS (aereal LiDAR) with standard options (default value "non-zero" in Global shift/scale and "Preserve global shift on save" clicked)
2) Deleted all normals (Edit > Normals > Clear), TLS sensor and Octree (nothing to do for this step, everything was already empty):
3) Checked the correct position where to insert the TLS using a point picker.
4) Installed TLS (Edit > Sensor > TLS/GBL > Create)
5) Checked the Cloud depth buffer shown
6) Checked the position of the TLS inside the point cloud
7) Saved the point cloud as e57
8) Imported the e57 in Reality Capture as Unregistred
The file was imported correctly in RC but it creates just 1 lsp with the TOP view. I was expecting the view from the TLS that I added in CC (and also 6 different views) . Something went wrong but I don't know what.
Thank you.
