Weird shadow problem

[RichardHessels]

I am editing an excisting track and have a strange shadow issue.
My shadowobjects are casting their shadows on the barriers under it but not on the road object.
But the car's cast their shadows on that same same road object perfectly.
Those same shadow objects do cast shadows on the car, but still not on the road.
Opening the SCN file in the latest 3DsimEd shows those shadowobjects working, casting shadows on those same roadobjects. But ingame it does not show.
Shadows are maxed out in the sim off course.

I tried every setting i could think but my simple shadow objects just wont cast their shadows on the roadobjects, but the cars do.

Before i keep pulling my heirs out, anybody got clue?

Look at the material properties and make sure the Emissive colour is pure black. If it isn't, shadows will be cancelled out, or very faint, and the material will remain lit in darkness.

Yes i did that.. its 00000, but i remade those faulty shadow objects myself, now they are working perfectly.
Something akward with the excisting objects, they where having multiple vertexes on top of each other.
Kept peeling layers off, many where projected inside out, till it thought just leave it, I make new ones.
