Ok, I'm working with refPlanes on my track and all seems to be ok for Bridges and Overhangs... but... ...I would like to better understand some details on refPlanes size, shape and positioning. 1) There are some specifications in size, rotation and Z position above the track? 2) If the istance to reflect it's not directly potisioned on the track side (IE: garages, Pitlane Towers etc...), where I need to put the refPlane? I need this infos just to know if I'm working the right way... Tnx...
