v1.17 Experimental II
Empyrion - Galactic Survival Patch Notes — May 13, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Hi Galactic Survivalists,
We want to give all mod developers an early heads-up regarding an upcoming change planned for next week's update.
We have successfully increased the maximum block limit in BlocksConfig.ecf to 8192. As a result, all item IDs used by the API (code mods) will shift accordingly.
If your mod uses item IDs in any form, you will now need to calculate them using:
Item ID + 8192
Failing to apply this offset will result in incorrect items being given by the API in-game.
Please note that the IDs inside BlocksConfig.ecf itself are NOT affected by this change.
We also want to point out the ModApi.Application.GetBlockAndItemMapping() call available in the V2 API (ModApi.dll). Using this method ensures your application always receives the correct item ID mappings.
The method is available on the Playfield Server.
For example, you could export the mapping to a .txt file and have your mod read from it dynamically instead of relying on hardcoded IDs.
We are announcing this a few days in advance so mod developers have time to prepare and update their projects before the release goes public.
Thank you for your continued support and contributions to the Empyrion modding community!
