A visual graphic issue: Grass through objects

[IckyATLAS]

It is really annoying to have the tall grass going through any object.

On the Kuban Map when you put objects onto the map where there is grass then you have the grass remaining as if nothing was put on top and going through any object (block) whatever the material, steel, concrete, wood, fabric. 

When putting an object on the map then on the map surface the grass should be visually eliminated where the object stands.

Another way round is that we can define with the editor patches of variable size on the map without grass where to put objects.
