I'm working on a texture pack at the moment, primarily for mekanism, and I want to try and make the power indicator wider- something more akin to the power bar that comes from cofh (The thermal series). I can't find the meta for doing such a thing, and simply editing the textures in the GUI folder doesn't work- just causes a lot of issues, really, because the thing has already selected a thin area for each bar, rather than the wider one that I want to use. Is there any file I can edit or add that specifies these properties as part of a resource pack, and if so, whereabouts can I find it?
