Re: [PD] Multiblob and matrices...
Hello, 2 examples +/- from help patches that may help ++ Benjamin Simon Ball a écrit : Thanks for the response. However, I am still struggling with this. I probably need a much more basic explanation. Sorry. I assume that the patches you've provided (greatly appreciated) collate the data in someway in order for me to be able to unpack it? However, I'm not sure that I even understand exactly how 'unpack' and 'route' work, which is obviously a problem! If anyone can provide a more simplified explanation I would really appreciate it. I'm not that familiar with programming, so layman's terms are all I can manage!
