Slight redesign.Managed to make it fatter, roof section shorter and fit in a top section of a smaller tunnel, running along, the main.
Now I can add small tunnels to join up the large sections.Thought I will keep the above tunnels, it just wasn't ideal.
Lol perhaps you guys would have liked to see the finished product,well I like to show step by step progress, as how I go along, designing a tunnels set.
I wished I managed to get a visually good tunnel set the first time around, but often you need to make several versions to work with, to get a feeling and scale, before settling on some thing best suited.
I am rather sad that the first tunnels set failed, due to collision issues, thought collision isn't terribly bad, but for a paid for project, it is simply not good enough even the slightest collision issue means a problem for the players.
That is all for now
