OTD
If you have spent hundreds of hours in ARK: Survival Ascended, you know the endgame grind all too well. You farm the same caves, hit the same supply crates, and pray for a decent blueprint. The monotony can be brutal. That is where OTD (On-The-Drop) changes everything. This add-on transforms the static world of ARK into a living, breathing ecosystem of timed loot events that keep players on their toes. Instead of predictable spawns, OTD introduces dynamic drop zones that appear, despawn, and respawn based on a timer you control, making every session feel fresh and rewarding.
This guide covers everything you need to know about OTD for ARK: Survival Ascended, from the core mechanics to advanced configuration. We will break down the mod ID, server setup, and the best practices for tuning the drop rates to match your server's population and difficulty. Whether you are a server admin looking to spice up the PvP scene or a solo player wanting a more engaging PvE experience, OTD delivers a layer of unpredictability that vanilla ARK simply lacks.
What Exactly is OTD?
OTD is a server-side utility that periodically spawns high-value loot crates in random locations across the map. Unlike the standard orbital supply drops, OTD crates are entirely customizable. You define how often they appear, how long they stay, and what kind of loot they contain. The add-on uses a simple INI file for configuration, meaning you do not need to be a programmer to tailor it to your server. The core appeal is the "timer" aspect: drops are not tied to a global schedule but to a respawn window that you set, creating a sense of urgency for players to locate and secure the crate before it vanishes.
For those running dedicated servers, the setup is straightforward. The mod ID is 996693, and you simply add -mods=996693 to your launch options. Once active, the GUS.ini file handles all the tweaking. The default settings provide a balanced starting point, but the real power lies in adjusting the timers and loot quality to fit your specific gameplay loop.
Core Features and Configuration Breakdown
The beauty of OTD is in its granular control. Let's look at the primary variables you will be editing in the [OTD_Ini] section. These settings directly impact server performance and player engagement.
Timers and Spawn Rates
- OTD_AccessTimer_in_Sec: This is the cooldown between drop events. The default is 10 seconds, which is extremely aggressive. For most servers, you will want to increase this to several minutes to avoid loot saturation.
- OTD_RespawnMinTimer_in_Sec / OTD_RespawnMaxTimer_in_Sec: These create a random window for the next drop. With a min of 10 and max of 20 seconds, drops happen almost instantly. Setting these to values like 300 and 900 (5 to 15 minutes) creates a more suspenseful hunt.
- MaxOTD_Count: This limits how many active crates can exist on the map at once. The default of 20 is high; reducing it to 5 or 10 forces players to compete for the same resources, which is excellent for PvP servers.
Loot and Interaction Settings
- DropLife: Measured in seconds (default 15000), this dictates how long a crate remains on the ground before despawning. A shorter life (e.g., 600 seconds) makes the race to the drop more intense.
- LootQualityMin / LootQualityMax: These values (3 to 6 by default) scale the item quality. A max of 6 ensures ascendant-tier gear is in the pool, while a min of 3 keeps primitive and ramshackle items out of the rotation.
- LootCrateClass: This is the blueprint path for the crate itself. The default
OTD_LootCrate_Cworks out of the box, but advanced users can swap in custom crate classes for unique visuals. - StructurePrevention: When set to
false, players can build near the drop zone. Setting this totrueprevents foundation spamming around the crate, which is a common tactic to block access. - AllowUnderWaterSpawns: Keep this
falseunless you want players diving for loot, as underwater crates are often inaccessible or frustrating to retrieve. - StructureCheckRadius: This works with StructurePrevention to define the exclusion zone (default 10000). It checks for player structures within that radius before allowing a spawn.
How to Install and Activate OTD
Getting OTD running is a two-step process. First, you need to subscribe to the mod on the Steam Workshop for ARK: Survival Ascended. After that, the configuration is king. Here is the quick rundown on how to install it effectively on your server.
For a dedicated server, navigate to your launch parameters and append the mod ID. For a non-dedicated session, you can enable it in the host menu. Once the server boots, locate your GUS.ini file in the Saved/Config/WindowsServer directory. Paste the [OTD_Ini] section into that file and adjust the values to your liking. Restart the server, and you are live. If you are looking for a hassle-free way to manage this, consider using a launcher that supports mod integration. For instance, the foxygame.net launcher offers a streamlined add-on catalog that lets you manage OTD and its configuration files without manually editing server directories, and it automatically checks for version compatibility with the latest ASA patches.
Compatibility and Server Performance
OTD is built for the Unreal Engine 5 version of ARK, meaning it is fully compatible with the current ARK: Survival Ascended versions. It does not conflict with most popular QoL mods, such as stack size mods or custom dinos, because it only spawns its own unique crate class. However, you should be cautious when using it alongside other loot table overhauls. If two mods try to control the same supply crate spawns, you may see duplication or missing crates. OTD is designed to be standalone, so it is best to disable other crate-altering mods to ensure stability.
Performance-wise, the mod is lightweight. The primary overhead comes from the StructureCheckRadius calculation, which scans the map for foundations. If you have a massive server with thousands of structures, you might want to lower this radius to 5000 or 3000 to reduce server tick lag. The MaxOTD_Count also affects performance; having 20 crates with a 15000-second life means the server is constantly tracking their timers. Reducing this count to 10 or less keeps things smooth.
Balancing OTD for Your Community
The default settings are tuned for chaos. A 10-second respawn timer and 20 concurrent crates will flood your map with loot. For a balanced experience, start with these adjusted values: set OTD_RespawnMinTimer_in_Sec=600 and OTD_RespawnMaxTimer_in_Sec=1200 (10 to 20 minutes), MaxOTD_Count=5, and DropLife=900. This creates a scenario where a crate appears every 10-20 minutes somewhere on the map, lasts for 15 minutes, and only five can exist at once. This encourages exploration without making the game trivial.
For PvP servers, lower the DropLife to 300 seconds and set StructurePrevention=true. This forces tribes to make a split-second decision to leave their base and contest the drop, knowing they have a limited window. For PvE, you can keep the loot quality high but extend the DropLife so solo players have time to reach the location.
Final Thoughts on OTD
OTD is more than just a loot crate mod; it is a server management tool that injects excitement into the daily grind. By mastering the INI settings, you can create a dynamic world where every hilltop might hold a treasure and every timer tick is a call to adventure. Whether you are a veteran admin or a new host, download OTD and experiment with the timers. The default configuration is a great starting point, but the real magic happens when you tailor the spawn rates to your community's playstyle. Give your players a reason to log in and explore again.
Ultimately, OTD bridges the gap between the static nature of vanilla ARK and the chaotic, rewarding experiences found in modded survival games. It respects the core survival loop while adding a layer of high-stakes gambling. So, tweak those timers, set your loot quality, and watch your server come alive with the hunt for the next drop.
