Procedural generation of 3D cave models using Unity

To start the generation, select with the left mouse button the vertices that will represent the cave gate. The Gate size parameter represents how many of this gate vertices will be. Once all are selected, press right mouse button to start the generation. There are other generation paramaters available, which will change the cave shape
