Author:Greg Lewis(<email removed>) This is a demonstration WAD to show how it could be possible to make an area (or areas) of a leve appear and dissappear, using a trick with the F_SKY texture. All you really need to do is make a door, with F_SKY1 as the ceiling texture, and have the door sector's floor level with each of the surrounding sector's floor. There are a number of small details to take into consideration too, to make a convincing illusion. But, once it's mastered, I think some interesting stuff could be done with this. Matter of fact, I might use it myself, if I ever make another WAD... :) Also note it might be a good idea to use the generic "starry sky" replacement for the sky, to remove the possibility of seeing the bottom of the sky texture. This was made with Doom I, but is easily converted to Doom ][ (just change E1M1 to MAP01). Any questions? Contact Greg Lewis (Tree) at <email removed>. Reality? Who needs it?
