When using the E57 writer,I've been unable to assign specific names to the scans in the point cloud file.In my case I only have three names,and those are in attributes waiting for a place to use them.
It seems the writer uses the file's basename for the first scan,and then appends _001,_002,etc.to any others.
I'm hoping there's more flexibility and that some smart person will tell me where to find it.
TIA
