Modding tools would let you 'see' all the invisible textures in the game. They are used for many things like preventing people from walking through, preventing weapon fire from passing through, preventing vehicles from going by and other things. However, I don't think a map modding tool would let us see the results of a player pressing block.
I think RedTech is saying, when you press the block button, an invisible texture is created infront of the Jedi which blocks/reflects all incoming fire. The tools would let us see this texture. Because the Jedi block ingame, I don't think the tools would display this texture (as it is not during a game).
