Stained glass will not be in 1 . 0 . Well , it kind of will , because the glass used in End Cities IS stained glass , but it currently just uses the default glass texture because rendering semitransparent objects is hard . not because rendering a semitransparent is difficult , but because rendering semitransparent objects behind other semitransparent objects IS hard . This isn ' t just a Minecraftspecific problem . you may notice how VERY few 3 D games use semitransparent objects . most of the time they use tricks to make things look transparent , or make sure that semitransparent things never wind up behind or in front of each other . In Minecraft , you simply can ' t avoid the problem because its a sandbox game , and people are GOING to build stuff using stained glass all over the place .
