Problem Normal map in 3dsmax convexe and concave shapes

[hx.jonathan]

Hi everybody, :):)

I have some problems to bake a good normal map in 3dsmax for this object :

I only had modeled one quarter of the object and made a symmetry on x and y axis to have the entire object.

As a result, on the seams, I don't have a good result. I tried to enlarge he cage in the projection modifier but It doesn't work.

I use a 512 *1024 texture.

I also tried to bake it with xnormal but it is worth. I tried to chamfer the edge border but it doesn't work.

I used the lightracer to bake the normal map.

Can you advise me on how to bake correctly this kind of object ? Is there specifi parmeters to set in the lightracer (I used the dfault parameters).
