The documentation for jmonkeyengine says that it is not necessary for each texture to do material. Material determines the the other quality of object than texture. E.g. rock not glow...

Torch placing logic is very simple. - Torch placed in NON SOLID tiles with odd coordinates (x, y). E.g Point(1, 3), Point(5, 7) - Only one torch available in tile...

odd with our 0-based coordinate system. We must remember that some of the tiles already has a the light without torch

Some correcting my algorithm. X - axis place only odd x-coordinate on SOUTH and NORTH walls. Y-axis place only odd y-coordinate on WEST and EAST walls (something like this) 

Like so 

It should not. More specifically can, but not on this side of the wall (only on walls with blue lines)
