Ultra Stacks

Now includes items from Genesis DLC

Mod ID: 761535755
Current Version: 2.02 (Updated April 21st, 2020)

Includes stackable items for Extinction, Aberration, Scorched Earth, and Genesis DLCs

For established servers, please remember to relearn your engrams for certain changes to take affect. Please see the patch notes for more details on the changes in the latest update.

Ultra Stacks is a stacking mod for ARK Evolved. I know there are quite a few stacking mods out there, but the goal of this mod is to provide the best stacking experience possible to make the game more enjoyable. Also, my goal is the keep updating this mod as soon as possible, and for as long as possible. I know a lot of players get upset when mods don't get updated. I will always do my best to ensure this mod is updated as soon as a new Ark Dev Kit is released.

Not only does this stacking mod change the quantity and weight of items, changes have also been made to some of the spoiling times as well. Most spoiling times have been doubled, and other items have their spoiling time increased even more (e.g. prime meats).

If you are not adding Ultra Stacks to a new server, players may have to relearn their engrams before the stacking changes take effect. This issue will not occur if you are adding Ultra Stacks to a new or wiped server.

This mod is completely stackable, but it is not compatible with any other stacking mods (you should only be using one stacking mod on your server to avoid complications).

Works with multiplayer and single player servers. Also includes stackable items for Extinction, Scorched Earth, Aberration, and Genesis DLCs.

UPDATE: For server owners who are experiencing the Iguanodon seeding issue when using stack mods, it can now be fixed by using the following mod below with this stack mod:

Iguanodon Seed Trainer

is there a way to alter stack sizes?

Some items don't stack, or just stack less. Thatch for example. Can only get a stack of 200. Is it a glitch?

Until Primal Crystal is added, I'm currently using the following line in my game.ini file.

ConfigOverrideItemMaxQuantity=(ItemClassString="PrimalItemResource_Crystal_IslesPrimal_C",Quantity=(MaxItemQuantity=100, bIgnoreMultiplier=true))

It isn't perfect for certain, but it does at least help slow down the decay since they're stacked.
Things like Automated Ark still pick them up one at a time though so if you use that mod, just expect to handle your primal crystals separately. Best to keep them on a wyvern with plenty of food though since that's the only way to prolong their shelf life right now.

is there a way to edit the amount of weight reduction to the items in a .ini somewhere??

Running this on my CI server without any issues really. The only issue i have found is that mutton stacks aren't not working with the Immersive taming mod, all other stacks seem to be working fine. The immersive taming bait station doesn't recognise mutton at all.

Crystal isles content currently isn't on the dev kit (maybe another week or month), so primal crystals can't be added. UNLESS the mod creator has some special other way.

Update for Crystal Isles stacks? Prime Crystals
