Awesome utility! I use it to convert OBJ files I strip with Blender to make cool new ships.
Note that the install instructions for linux did not work for me. No such thing as a Pip3.6 command, so I created my own install instructions here, if anyone is interested:

Also NOTE that you cannot use the latest version of StarMade with this! You must use a pre-systems 2.0 version. I use version 0.199.654#20170826_140955
I would appreciate it if you could give me a detailed description of the crash. Either write me a pm, or make a post: https://starmadedock.net/threads/smbedit-blueprint-editor.29406/
