Alec, I was using the script from the link below to set my max hard edges to the likes of maya, as I was under the impression this was the correct way. This was causing the error in HP. http://www.polycount.com/forum/showpost.php?p=1760374&postcount=46 With that said I did more testing because of this and realized that…
I was wondering if it was possible to use Handplane is a sort of batch mode ? I didn't found any sort of documentation on the official website about this. I would be very interested, especially to link Handlplane to one of my maya script (froXnormal).
