Hi, this question has been coming up more frequently lately, and I totally get why. I’ll definitely try to add support for more export formats when I find the time. Thanks for the suggestion!
I think the best one to start with would be STL, since it’s the 3D printing standard and main 3D packages such as Blender and Maya have decent importers for it so it can also be used for regular 3D export. PLY is good, but not all 3D software support it well.
