A derivable T-shaped wall that fits in with Neva's other walls.

Note for developers: This wall takes the same texture maps as the PlainSquareWall, product 406691. You can download the maps here:

• Material 0 (A walls), 1 (B walls), 2 (C walls). Each material zone covers two adjacent walls, so you can have different rooms with different style walls.
• Material 3 (wall edges)
