I'm developing an Action RPG from scratch using Unreal Engine 4. I switched recently from Unity due to UE4's source code access and vastly superior performance. Here's the progress with the dungeon generation so far.

First, I worked on implementing the Growing Tree algorithm with Unreal Blueprint. I learned a lot about maze generation algorithms from Jamis Buck and Think Labyrinth.

Grid small
The grid generated with 10x10 settings.
Grid large
The grid generated with 14x14 settings.

Tile Tests

I haven't decided what setting to use for the game yet. I'm experimenting with tile designs to see what looks good from a top-down perspective:

Scifi tiles
Some prototype map tiles rendered in Modo 801.
