CaveTweaks is a Vintage Story mod by Pseudonym_Tim. CaveTweaks reshapes Vintage Story cave generation with deeper, denser, better-connected tunnels, fewer shafts, and more varied layouts.
Why this mod is worth installing
This mod suits explorers and miners who want cave networks to feel less predictable and more rewarding without relying on constant vertical drops.
What CaveTweaks adds
CaveTweaks increases the presence of caves and makes their structure more involved. As you descend, tunnels are more likely to split into new passages, creating connected underground routes instead of isolated pockets. Cave entrances and passages are also integrated into the terrain more naturally.
Vertical cave shafts are reduced, making exploration safer and limiting sudden falls into deep pits. Deep tunnels taper more naturally rather than ending in an abrupt flat basalt floor, so the lower parts of a cave system look less artificial.
Cave density adapts to the world’s vertical scale: worlds with greater height receive a proportionally larger cave presence. The generator also uses Mersenne Twister randomness instead of the older linear congruential approach, producing more varied cave arrangements. Settings can be adjusted through the mod’s configuration file.
