QUESTION Adding pitboxes to existing track

[Cortez]

Hi, I'm trying to add some pitboxes to Valencia Street Circuit https://assettocorsa.club/mods/tracks/valencia-street-circuit.html. I'm using kn5conv to open .kn5 file, adding AC_PIT_x and AC_START_x in 3d software (Blender or Max, names are 100% good), exporting to .fbx and exporting to .kn5 by KSEditor (set up shaders too). After that all cars are respawn at the center of map, on the water and fall down, every car in the same place. For Blender I'm using Autodesk FBX Converter to change .fbx ASCII to .fbx binary.

Can someone give me a hint?
