VR Head Tracking problem with Mods

[KastaRules]

Hello, when I play ATS in VR using an original SCS truck everything works fine but whenever I use a third party truck I have a problem with the inside view: basically the head tracking goes kind of crazy whenever I turn my head. Needless to say it feels disturbing.

Perhaps in the modded trucks there is a missing line somewhere in the def/camera/unit/interior_xyz.sii which would enable the proper head tracking for the Oculus Rift?
Does anybody have any idea on the matter?

The original trucks have custom camera with almost no extra angle-dependent movement which is used with HMD. The modded trucks likely do not have it so the normal camera is used. You can remove the movement by setting g_hmd_no_artifical_movement parameter in config file to 1.
