Anyone can place a torch on a wall. This post is to explain some other methods of using light in your builds. 1; Under light. - just a term I call a light source that emanates from behind other blocks. for example; take a glowstone block, place one slab on each side of it and then place one slab not on the top of the glowstone, but one space above the top of it. This will light up the slabs around the glowstone but will not light up anything else surrounding the slabs. This same method works with stair blocks and can be used in different orientations to create some awesome effects. Now place some glowstone on the ground in a pattern, any pattern will do. Cover the entire area with slabs (quartz) directly above the glowstone, so actually on top of the glowstone this time. When the floor is completely covering the glowstone you will see the slabs all light up. This makes a bright floor and further in this post I will explain how to manipulate this effect with over light. Keep in mind that any slab or stair block will do the same thing - I said quartz as you will see more of the effect with this block. Then you can have a light source on the bottom and top rows of a wall, all the way across from one end of a wall to the other. Now place a stair or slab block in front of those rows of light and when completely covered this will light up one side of the stair block, or the entire slab block for the entire length of the wall. This does not light up the room, but gives a unique effect to a wall. Play around with this technique to have some fantastic looking walls. Keep in mind that walls do not have to be one block thick. If your walls are 3 or more blocks thick then you can make your walls have depth by leaving open spaces in the front part of the wall and have different blocks behind that give a nice visual. Put some light sources in side this wall to make it even more impressive. 2; Over light. - simply any light source that is not blocked by anything. In other words a light source that illuminates the surrounding area. Over light will always overpower under light. What I mean is this; remember the floors made with glowstone under quartz slabs. now over light will dampen the under lights effect on the quartz slabs.. Place a slab on a wall above this quartz floor and then place a redstone torch on that slab. Notice how that effected the light on the quartz floor. Again - play around with this idea to come up with some really cool floor patterns. Note that some things can cover your light sources without changing the effectiveness of their light dispersal. ex; a picture covering a glowstone block in a wall will not dampen the glowstones shine, but does effectively hide your light source. Carpets will also cover a light source on the floor without dampening it's brightness. More methods include making a small pillar of 8 blocks high with a light source in the center at the bottom. the light gives a nice shading effect to the pillar as it dims the further up the pillar it goes. These are just a couple quick examples of playing with light sources in your builds. There are many more techniques, so play around with these ideas to get yourself acquainted with their effects. I really hope this has been a helpful post - Be creative, ( try different things) Edited for those that need visuals - o'O There is glowstone with slabs and stairs around them that do not give off light but do light up the stair or slab next to them, an all quartz floor,( 9 blocks wide in the middle with glowstone underneath), that light is manipulating into a pattern. some slabs surrounded by green wool going along the side walls lit up by underlight . 4 torches that I have placed high enough so that only small portions of the floor change. Even the smallest amount of overlight will overpower underlight. The glowstone at each end gives the triangular pattern ends to the floor. As for diagrams. lol.. I do not use diagrams, or plans. Truth is I have no idea what I am doing.
