Hi Mario,

I'm going to try again to transform it in Mantra as you and Jason
suggest. That was the first thing I thought of, but the last time I
tried it I could not get the point clouds back into the correct space
when reading the .pc back into Mantra. It did appear correctly in
Houdini though.

Cheers,

Peter B
