The first pictures below show the new 64x32x0.5 stone wall made for TXP2. It's based on the new 4x4x0.5 stone wall (also for TXP2). More sizes will be made as soon as I've finished making a script for this purpose. The intention of making the different sizes is to let the map makers be able to create more complex (and glitch-free) structures. All the new stone walls will be textured and solid at the bottom side.
Below is shown 4 pics of one single 64x32x0.5 wall used to block off a valley in terrain dfg5...:
Below is shown three of the 4x4x0.5 walls stacked together...:
