Update 01.165

8 December 2016

Hello Engineers! We are very happy to announce that today, we have a massive update for you, the one that’s been months in making. There’s the total block redesign, new multiplayer netcode, a tutorial campaign and much, much more!

Total Block Redesign Nearly every art asset in the game has been redone together with the first iteration of render optimizations. This includes new block models, new weapon and tool models, new component models and new voxel textures. All of these assets now use physically-based rendering. There’s an incredible amount of models in the game so you can expect various bugs to be fixed over the coming weeks, and as always, if you find any sort of bugs, please report them on our Forums -

It’s worth mentioning that there will now be time to listen to community feedback on the new models so we can modify, adjust and improve them if required. Aside from the redesigned blocks, we also have a couple of completely new ones to add. These are of course the corner lights and corner LCDs (available for small and large grid) and created by Arindel so many many thanks to him! They really did help the level designers with creating the desired atmosphere of the missions.

Multiplayer It was decided that we would take the best features and technologies from all of the MP contestants and combine them into one ultimate multiplayer experience. This means that as well as the netcode and performance based features, it’s also bringing gameplay features like magboots and voice communication. Magboots allow you to walk all around grids in zero g, but only works if there is no natural or artificial gravity. Voice communication works within antenna range, and you can chain together antenna networks to increase your range. Thanks to Rexxar, there are more advanced admin tools in the Space Master menu. This is just the first iteration, and more tools may be added in the future. We’ve also redesigned permissions ingame, adding new Scripter and Moderator roles. For more details on these features, check this thread. There are some important and exciting modding changes this week, including a new way for mods to store custom data inside entities, please see the link below for more details if you are modder or a scripter.

Campaign Next up, we’ve got the tutorial campaign. This is a short campaign mainly designed to help new players get into the game - but should be a lot of fun for existing players too, as it’s a great showcase of the storytelling potential in Space Engineers. We hope you will enjoy it and that it will inspire content creators out there to design their own missions and campaigns. They have all the same tools that our in-house designers have at their disposal like triggers, cut scenes, drone AI and more.

Drone AI Thanks to the tutorial campaign, we spent some time improving drone AI. They can now strafe, attempt to ram when out of ammo, use static weaponry, have more specific targeting and be assigned waypoints. Currently these features can only be utilized in your own drones via the visual scripting tool.

Drive-by Turret Shooting One of favorite features that we’re also adding this week is the ability to control a single automated turret while still driving or flying a vehicle. The only requirement is that you set one cockpit on a grid as the main cockpit. Once controlling a turret, you can aim it with the mouse while using the WASD keys to steer the vehicle. By holding ALT, you can switch back to controlling gyroscopes with your mouse. We’ve also cleaned up camera overlays and added a zoom function to all automated turrets to help you make that crucial shot.

...And More! We’ve added the ability for bullet decals to be seen from the inside of cockpits so now you will really know when you’re getting hit. We improved building by making the block size get automatically selected by the grid that you are pointing at; you can change the size manually by pressing the block button on your toolbar again so you are still able to create a new grid from any block. Lastly, you can now interact with highlighted blocks by pressing LMB and interact with control panels by pressing RMB.


  • New Multiplayer netcode; best features were merged from all the MP contestants
  • Total Block Redesign; every block has been completely reworked (textures/LODs/etc.)
  • New and redesigned Tools and Weapons look
  • New and redesigned look for Components, Voxels
  • Physics improvements
  • Render improvements
  • Added Campaign containing 5 missions
  • Added Voice Chat (dependent on antenna network, it can be enabled by pressing U)
  • Added Magnetic Boots
  • Drone AI Improvements (strafing, ramming when without ammo, can use static weapons, targeting, waypoints)
  • Drive-by Turret shooting (shooting from turrets while moving with vehicles/ships)
  • Improved building (block size is automatically picked by the grid that you are pointing to; you can change the size manually by pressing the block button on your toolbar again)
  • Interacting with highlighted stuff by pressing LMB and interacting with control panel RMB (only with empty hands)
  • Added Corner Lights, Corner LCDs (thanks Arindel!)
  • Enabled interior lights for small ships
  • Added Advanced Admin Tools in the Space Master menu (thanks Rexxar!)
  • Redesigned permissions ingame, added new Scripter and Moderator roles
  • Created a new way for mods to store custom data inside entities:
  • Added Zoom function to all turrets
  • Decals are now visible from inside the Cockpits
  • Voxel hand can be used by Space Master


  • fixed issue where welding with multiple welders cause major sound and performance issues
  • fixed desync for warheads on dedicated server
  • fixed crash at ParallelTasks.TaskException when pasting blueprint
  • fixed crash at System.Array.Clear
  • fixed aiming issues for drones
  • fixed crash when two merge blocks that were part of the same grid merged
  • fixed crash at Sandbox.Game.Entities.Character.MyCharacter.EndShoot
  • fixed crash at Sandbox.Game.GameSystems.MyGridCameraSystem.ResetCamera
  • fixed crash at Crash at System.Collections.Generic.Dictionary
  • fixed minor issue with cameras and chat function
  • fixed issue with LCD panel crashing the game when removed or grinded down
  • fixed issue with being able to produce infinite hydrogen with the stockpile option

Update 01.143

7 July 2016

Developer Button.png


New This week’s update brings another round of bug fixes and improvements. We're also trying something new today, bringing you the first in an upcoming series of Space Engineers dev diaries. In the developer diary this week, our programmer Michal will tell you a bit about animations he's been working on, particularly the new things he's added and some of the final touches on the system. Right now we support synchronizations between layers and also support reading variables from the environment, so the animation is completely driven by the game and not vice-versa.

Michal is working on stabilizing the first person camera and smoothing out the behavior of the 3rd person camera, and he will also show you the inverse kinematics for the feet of the character. This means that if you're running on an asteroid, the character snaps his feet correctly to the surface of the asteroid. This also applies to animals (for example, spiders). He's also improving the weapon animation and positioning in the game, which should be much smoother than before.

Finally, in the 3rd person, we're using animation from our artists rather than the code. This improves appearance while running. We can also use animation for driving the weapon position for complicated situations like holding the weapon while running.

We hope you enjoyed this new segment and though we won't have a dev diary every week, you can look forward to more in the future!

Update 01.142

30 June 2016

Developer Button.png


In this week’s update we are releasing a revised building system. From now on, you can create a new grid from any block (not just from landing gear) by simply placing a block in any open area. We’ve also made changes to the G screen by cleaning it up, organizing it, and grouping similar blocks into groups. You can see if a block type has variants by the plus symbol in the top right corner of its thumbnail. To switch between variants, use the mouse scroll wheel. These changes should make building much more intuitive and time efficient.

Zooming in and out of 3rd person view now requires you to hold Alt combined with the mouse scroll. Also, any grid that is pasted into voxel from the clipboard will now become a static grid, including small ships. You can place them in at any angle and orientation.

Please note that because of the changes we made to the building system, we had to make adjustments to how blueprints are projected from projectors. It's now based on the first placed block of a blueprint. This means that the offset values in projectors will have to be corrected to account for this in all existing creations.

Lastly, the major improvements for the ModAPI and ingame programming mentioned last week are going live today. If you are a modder or a scripter who missed that announcement, here is the link to the ModAPI/Ingame Interface Expansion and Improvements guide:

We would like to say a massive massive massive thanks to Malware for completely replacing the script compiler and to Phoenix84 for all the modding changes :). We cannot thanks guys like this enough!

If you want to place individual block variants to your toolbar, you still can - just text search for the block name in the G screen and place it directly to the toolbar as usual. (so you do not scroll through each armor block variant to get piece you are looking for)

This week’s update brings a new batch of bug fixes and improvements. Firstly, the update now allows you to turn off solar panels. Bugs fixed this week include projected antennas broadcasting, incorrect construction stage orientation for some blocks, cockpit toolbar issues, and the control hints cube being stretched. We’ve also fixed a number of crashes caused by changes to the planetary code last week.

Next week some major improvements for the ModAPI and ingame programming will be released. However, this will break scripted mods and some ingame scripts. If you're a modder or scripter, please see the guide linked below for what you'll need to do to fix your mods. Finally, keep in mind that all the changes in today's update will only be on the weekly development branch - you will not notice these if you are playing on the default stable branch.
