PMDG 737 NGX Nose/Roof/Side Texture Alignment

A vast internet spanning a gazillion terabytes and no one has ever made a written or video tutorial about how to get the front end roof, sides and nose textures to align properly on the 737NGX paint kit.   Is there a gem out there I am missing?  Every single YouTube tutorial on painting the NGX is done with an easy livery that requires no thought what so ever about the front nose and roof texture alignment.   When one paints a very detailed no repeating texture or gradient fill on the front, aligning textures becomes a nightmare I have discovered.   The concept of how the sides of the plane bend down and the roof texture bends with it but splits apart at the seams on the 2D texture map is just breaking my brain.    Is there no easy way to get a complex texture to align right?  Are we stuck with solid color paints on the roof and nose for life?    

I have been struggling for days to finish up this Frozen One livery but I can't get rid of the front nose seams where the sides and roof come together.  The entire plane is painted to be covered in ice crystals and snowflakes which creates unique patterns which do not align on the nose of the plan worth a darn.   I can't find any tutorials on overcoming this problem.   Anyone else find one?
