There have been a number of additions since the last post when I released the public playable demo from new levels to additional features. Those of you who have worked with Unity know that the terrain system is fairly limited. Thanks to the Relief Terrain Pack (shaders for terrain) and some clever code work to set certain layers to ignore collisions with each other, I now have traversable tunnels (an older feature) with visible holes cut in the terrain (the icing on the cake) to complete the illusion.
Additionally, I added the ability to highlight the path of said tunnels so that the player can see where they are going. The following gif was of the rough concept – it has since been cleaned up to differentiate walls from floors.
