Try this way. ◙ Export to rF1 in a folder outside of development mode <with the name you want the track to have> (this will save you work later). ◙ Create the structure <with whatever name you want the circuit to have> in moddev locations. ◙ Edit the original SCN and delete the lines corresponding to the sky. ◙ Copy SCN, TDF, AIW, CAM and GDB to the new folder. ◙ Import in 3dsimed the rF1 scn. ◙ Export GMT rF2 to the new structure. ◙ Export the textures to the new structure. ◙ Edit the new SCN to update the search paths with the data of the new structure. ◙ Import the new SCN into 3dsimed and check that everything is displayed correctly and use the info tool to check that no objects or textures are missing. ◙ If there are no errors you should be able to start rF2 in development mode and charging the circuit. From this moment on you are ready to start editing everything you need, include animated objects, modify shaders / textures, etc. (the latter I do from rFactor Devmode as you can see the changes in real time and the adjustment is more accurate). I think I am not forgetting anything, I have related the process from memory.
