This should be solved by properly configuring the Render Queue material of your objects.

I have created 3D Map - Tileset in my project.
and we are using 3D marker prefab to set the waypoints, which are 2d texture, instead of 3d sphere mesh.
the problem i am facing is that the 2d texture is overlapping with the map.
I have attached a png image of the problem i am facing in this thread.
please can you suggest the correct way to handle this situation so the overlap does not happen.

Any suggestion would be of great help

Thanks.
