How to know/set the index in Blender?

I am not a blender expert, so I do not know how, hopefully someone else can answer. For now, what I do is either:

  • In Blender, add a small node with a mesh (e.g. a small cube) attached to the point on the 3D model that I want to attach to in C3 and use the 0 index of that node/mesh (since it is small it doesn't matter which index is used.)
  • In C3 iterate the index during runtime to see which index is most appropriate for the point I want to instrument / attach to.
