About this project
What does VK's Ω-Stacking [VKOS] add?
Join the Discord to help keep the science alive!
Utilizing around 67 mixins, we finally have it!
Omega-Stacking makes stuff default the stack size to 2.147B, for all items that stack beyond 1, so your favorite tools, etc. aren't messed with.
Of course, there are some things that are deliberately not touched. furnace outputs for example still remain at 64. many custom GUIs for machines in other mods also may not work with these large values, but everything should work safe enough for inventory and vanilla/sophisticated storage uses.
And this should also work with all of your favorite mods too!


There is one bug though, auto-sorting with sophisicated storage will delete items if they would sum beyond 2.147B. but, youd probably never obtain that many items anyways, right?
It is also configurable, all you have to do is set the max value you wish and restart the server.
Thats all I really have to say for this. This is mostly a companion mod for a new project of mine.
