Hi David,
Thank you for replying (so comprehensively), I appreciate it a lot!
Yes, I've already bumped into the python2/3 problem, when I wanted to use loom.
After I've sent the first message, I managed to compile a mesh to cms (haven't tried to implement it into a map yet, tho) but your explanation about the pipeline helps a lot. I'll try to make it work.
Also thank you very much for offering some additional help - I am sure I'll ask more.
Have a great day,
Kristof
