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

@Araxel: That you can do yourself actually. Just tinker with ConfigOverrideItemMaxQuantity in Game.ini and you can define stack sizes for all/anything you want and keep the vanilla weights for each resource.

Failmod, not working

Hi, is there any way to keep using big stacks numbers, but not having that ultra big weight reduction? Like, having the normal weight for each item of the game, but the possibility to stack them in big numbers.

@Mathmatics: There are several mods or ini changes you can do to alter beacon drops. Make sure you dont use any mod that does this or any setting in your inis for the same. This mod however does not alter anything in the beacons, only stacking/weight of resources.

I have a private Nitrado server. I started the server with this mod, SS, and classic flyers. The problem I have having is weird and I have not been able to find another example of. All of my red beacons have samey loot. Im talking 5 Lymantria saddles on the regular. Lots of mantis saddles. Never any other saddles. The problem is also with yellows but not as bad. Has anyone experienced this, with this or any other mod? Its really annoying id love to figure out the issue.

@™R.I.P™: Are these items that usually dont weigh much anyway?
™R.I.P™ Jun 1 @ 5:43pm 
This mod is very useful for me. However, there are some resources like hide, thatch, fiber, etc. that change stacksizes but do not change weight at all. Their weight is still the same as the original one. I wonder why?
Anyway, thanks. This mod makes my life easier.

@Petya: Stacking any kind of poop causes more problems than not, so most will not stack it. Including this mod.
