I think the best advise I can offer is do your best to mirror a mod that has the passenger seat already working. Perhaps one less complex than the R4045. Pay particular attention to all the nodes referenced in the passenger seat lines in the .xml of the working mod. Then, to get the camera and make sure it’s right, import that working mod in GE into your 9R i3d. Then identify all the camera/nodes you need from the working import, select them and use the center mouse click to drag them up into your 9R. Now build the lines in your 9R xml to match the working mod but replace the nodes with the new node locations you just made in the 9R. There is lots of other tweaking of camera location and other things. There’s no good way to describe all this via text. Find me on Discord and I’ll be happy to answer more questions. Good luck!
