Hi Thanks Sunni! I had a long chat with Martin this week and he basically told me: “Tim you are an idiot, 3D Billboards are not the same as real life billboards, they should always face the camera” :-)
So now I am convinced but still not sure what will actually be put in the billboard i.e. how will I configure its contents based on some data from my layer? Thanks!
