Problems with shadows

I have managed to produce shadows in Relativity for some tables and chairs I made with a .prp file
But I try the same thing with with the Stonehenge with out a prp file I get nothing.
I put a shadow light component on one of the lights and a shadow caster component all of the stones and it dont seem to work
I tried merging the tables chairs light and the two shadow components into a test age and still no shadows
I give up I can not figure it out I need help, I dont know blender and not many people here that I know of are using 3ds max
I can do the shadows for the AV just fine but AV shadows and no shadows from the stones looks wrong.
I know its something simple I over looked I just cant figure out what it is.
