Translations:GregTech 5/Mining and Processing/2/en

GregTech ore blocks do not work exactly like other ore blocks. Most mods treat their ores as single blocks, with nothing special to them except for the few that must be silktouched or can be fortune mined. All GregTech are non-ticking MetaTileEntities, defined not by block ID or metadata but by TileEntity data. Each of these TEs contains only two variables: the internal ID of the ore, and a True/False boolean denoting whether the ore block was placed by world generation or by other means. This is mainly used to determine whether or not a Small Ore's drops can be enhanced by a Fortune pick. Their being TEs though has some unfortunate consequences: not all mods are prepared to deal with TE ore blocks, and so GregTech ores are not always mined by other mods' automated mining systems. (For example, for several months, the  could not mine GregTech ores.) The most unusual consequence of the ores being MetaTileEntities is that GregTech MTE rendering is done by combining a base texture with an overlay. When viewed at steep angles, those overlays can exhibit some odd rendering behavior, either looking like black lines, white lines, or oddly transparent. It's hard to say exactly what the visual effect looks like, but once you've seen it once or twice you come to realize that it looks wrong, and that its looking wrong is a telltale sign of the presence of ore.
