Often in games I see castles with square or round towers, but there is another type - a “D” shaped tower sometimes called the “Welsh Tower”. The square tower was vulnerable to tunneling and undermining at the corners, the circular tower had a diminished active space for living and storage and required circular stairs.
The “D” tower was a compromise - square facing into the castle and round facing out.
So here is a creation of mine : The Welsh Tower
With the initial camera, you can see the two D towers at the gate house - a typical use.( see images below). You can change cameras by hitting the “c” key to walk around the terrain or the walls. The round corner towers are a mesh and 3 instances, the round mid wall towers are also a single mesh and 3 instances. The wall pieces are instances too apart from one small piece at the back. The 24 doors and the 60+ rocks are instances.
In smaller castles the D tower could be a keep - the castle centre stronghold. see Ewloe Castle here
Now the second piece of history is the terrain - it actually exists and was created using a grey scale height map. The terrain and the events that happened there have a place in movies (“The Vanishing” on Netflix) TV serials (“The Horror of Fang Rock”) and even video games (“Dark Fall - Lights Out”).
The islands are the “Flannan Islands” and in the 1900s it had a lighthouse…In December of 1900 the light went dark, and when a rescue ship reached it on December 26th. the 3 lighthouse keepers could not be found. To this day, nobody knows what happened there.
The terrain was created with a grey scale height map of those islands.
