Load heightmap automatically

Hello Everybody,

is a couple of days I have trouble regarding this matter. I have designed a large map (16 miles squared) using photoshop. I have saved it as raw format and I can easily load it as terrain clicking on import raw.

I would like to apply this action to all the 64 pieces that compose the map ( i decided to cut it into pieces because of its space). I already found a way to cut my 2d photoshop map into pieces, each one described by specific coordinates.

Is there a way to load automatically, in the editor only, the terrain grid included the heighmap? I can easily load and place each terrain using MENUITEM, so that the terrain appear in my hierarchy, but I am unable to load heighmap from menuitem.

Thank you for your help and attention,

Kindest Regards,

AB
