I fixed it this is the material i created and it worked perfect !!
This is the template for each layer and you can create ne layers by switching only the texture. It is simple and works. You do the same for the normal maps. Then you apply that material on to the terain and start painting.Atleast this thing works for me.
I think you can Highlight this post as a solution on the problem for now.
Thank you for the help !!!
