Tuesday Toot!! | Cave System Map Generator in Excel

Tuesday TootG+ is closing closed. When it was alive things happened. Things unexpected. Great things. Whilst my creative output is only modest, I thought I’d hold something up into the living light, something that came about purely because G+ existed … This is a toot to G+.


One level

Random cave system

I toyed with this idea but never really finished/refined it. This Excel cave system generator basically uses the bones of my random hex wilderness generator engine to make a randomly generated cave system. Like its parent file, there are some global and regional controls to vary the outcome of the cave system. But, overall, as a proof of concept, I simply tweaked a few settings to see if it could be done. I did consider stacking layers of these and interconnecting them to make a wider cave system, but …

I suppose if there is any kind of demand for a finished/refined version of this, I guess I could figure out where I was up to and finish/upgrade it. Let me know?! That said, if all you want is to generate a simple random cave system on a broadly hexagonal-like layout, it does work.

Three depths

Colours indicate depth

I also made a multi-coloured version of the cave generator. The colours are intended to represent different depths, eventually leading down to water.

These cave generators could be used to make an individual cave system, or to make a ‘global’ map for a wider ‘Underdark’ domain, i.e. ‘Veins of the Earth’ style.

If you want to mess around with the ‘work not currently in progress‘ Excel file, it can be downloaded here:  Link
