To execute the ObjTiler, use the flag -i followed by paths of OBJ files or directories containing OBJ files
obj-tiler -i <path>where path should point to an OBJ file or a directory holding a set of OBJ files.
The resulting 3DTiles tileset will contain all of the converted OBJ that are located within the files, using their filename as ID.
This command should produce a directory named obj_tilesets.
