I need to use a visible non-solid shader, how do I make one?
 
 It will be like the part of the last level in JO where if u follow Desann's shadow you fall into a bottomless pit. 
 -thanks
  
 
  
  
    textures/mymap/mytexture
 {
 surfaceparm trans
 surfaceparm nonsolid
 {
 map $lightmap
 }
 {
 map textures/mymap/mytexture
 blendFunc GL_DST_COLOR GL_ZERO
 }
 }
