Blog Feed en Thu, 14 Feb 2019 19:32 CET is a Medieval Engineers servers list. Its goal is to provide an efficient way for players to find a server that suits their needs and also for servers owners to get more players on their servers. 60 Update 0.7.1 - Major Overhaul of Audio, Visuals, & Blocks Thu, 14 Feb 2019 19:32 CET

Hello, Engineers!
We’re thrilled to announce that the 0.7 update has arrived and it’s filled to the brim with tons of exciting new features and enhancements! Whether you’re looking for updated block visuals, new blueprint building in survival, improvements to multiplayer or modding tools, there are plenty of fantastic new additions to experience in Medieval Engineers!

We are extremely proud of the work that has gone into the design of 0.7. The models -- and many aspects of building in the game -- have been redesigned from the ground up. Today we unveil this, and leave 0.6 behind. We recognize that with such a huge change, there will still be bugs, errors, imbalances. But given that Medieval Engineers is still in Early Access, we wanted you to jump in, see how it works, and help find the things that don't work right. If it ever becomes too much, you can switch back to the stable 0.6 branch as always!

Block Visuals:
We have remodeled and retextured almost everything when it comes to blocks. You’ll notice that there are no longer any hard edges. We have introduced parallax shading to bring more depth to the blocks without increasing the triangle count, ensuring the performance does not degrade. Additionally, we re-added some old blocks that got lost (wall with double-window with a pillar, etc.).

Updated Trees:
The trees in Medieval Engineers also got a makeover. There are new pines, new spruces, and oak trees!
Tree cutting has also been tweaked, so go check out those new oaks and don’t forget to yell timber when you cut them down! ;)

Female Engineer:
The female engineer is looking better than ever, as we’ve incorporated some of the features from the Space Engineers female engineer. Likewise, her body proportions look much more realistic.

The grids in Medieval Engineers have received a lot of updates, as we overhauled the entire grid codebase, removed multiblocks, optimized adding and removing blocks (grid splits and merges) on very large grids, simplified many systems, fixed small grids not sticking to large grids, improved block placement along with structural integrity and stabilized physical constraints (ropes, catch blocks, etc.).

We have upgraded the multiplayer behavior, especially with regards to the grids, to ensure they are sent over the network quicker, and fully connected, to prevent grid desynchronization, ropes getting cut, and other horrible scenarios that would cause clients to freak out. Serialization is now much faster in multiplayer. There is also better entity grouping to ensure grids load in together, which combined with lots of minor fixes, should significantly improve bandwidth.


Blueprint Building to Survival:
With the simple click of a button and a few swings with your trusty mallet, players can now add large buildings, such as castles to a survival world, as well as small constructions, including catapults, which are ready for action! Plus ropes and connections are now saved in blueprints. Blueprints now automatically store, and display, which mods are required, so you can always see what you may be missing when you place a blueprint. It also checks for research, shows you the resources needed to build it, and provides an easy way to check your progress. You can now work together with your friends in building your town!

World Chunking
World chunking is a new system that unloads objects that are very far from players. By doing this, we managed to vastly accelerate world loads, particularly for really large worlds. Dedicated servers should also see a reduction in memory usage. On top of this, it removed the need for abandoned grid decay, abandoned grids are usually not loaded into the scene, and thus do not consume any performance anymore. You can go explore servers and discover all kinds of ruins and structures left behind by people!

This vastly accelerates world loads, saves and unloads entities that have no players nearby, thereby reducing memory usage and performance loading. It also removes the need for abandoned grid decay; abandoned grids no longer take up any performance.


Be sure to check out the new main menu, blueprints screen, crafting screen and medieval master screen. Every other aspect of GUI has been retouched to fit this new style for the game. It’s not only visual, every screen also had careful thought put into it about what we want to show, in order to improve the flow of user interaction.

Medieval Engineers has never sounded so good! Lots of places that were missing sound now have sounds. We also improved the sound quality in many instances, and we added effects and filters, such as reverb and low-pass filters.

Under “the hood” of Medieval Engineers, there are rendering Performance improvements and GPU particles. There are also better visuals for sunsets and sunrises, and improved logging behavior to help us catch more bugs.

For our amazing community of modders, we have a nice list of new tools for you:
-Crafting system refactored to support world chunking and more, see this guide for more info:
-ModAPI dialogs
-Dynamic environment system access
-Added support for underground and inside checks to environment rules
-Programmable animation layers (thanks to Equinox)
-Navigation mesh session component (thanks to Equinox)
-Seedbags now support seeding on non-farming voxels and can plant non-farmable items.

While we are working out the kinks in 0.7, it may be worth creating 0.6-based copies of your mod so servers that want to remain on 0.6 for a while longer are able to continue playing without too much disruption.


Last, but certainly not least, we have a voxel hand that obeys landscaping stakes. This was a highly requested feature from the community to fix trouble spots when landscaping.
We hope you enjoy all of these new additions to Medieval Engineers, as we know that we’ll enjoy seeing what you create with them. :)

Thanks for reading!

Medieval Engineers: Year 2018 in review, plans for 2019 Wed, 02 Jan 2019 13:43 CET

2018 was a very productive year for Medieval Engineers. Just as with Space Engineers, Medieval Engineers also switched to the major update approach. We started the year with the introduction of the log walls, and performance improvements through better handling of parallel logic. We also introduced a pretty major feature for the modding community: the ability to make mods have a list of dependencies! This has made the modding community more tight-knit as they started to work together on higher quality mods.

Update 0.6.4 Patch 4 – Merry Christmas Tue, 18 Dec 2018 19:08 CET

Hello, Engineers!
Another year has flown by. 2018 has seen lots of improvements to the game, from the optimizations to player characters, allowing dozens of players on a single server, to a major combat overhaul, and some major improvements to the modding interfaces, allowing for fantastic mods like the Water mod and the Rails mod, it sure has been a ride.
Today we’re adding the banners of the first and second place winners, WarNexxus and Ivan Cornelius, and re-enabling the Christmas Tree crafting recipe. You will be able to decorate your buildings with your own Christmas tree again!

Internally, we continue to work on 0.7, as well as celebrating the holidays with our friends and family, here in Prague, or for those of us who are going home, in their home countries.
Enjoy the update, and happy holidays from the Medieval Engineers development team, and all of the people working at Keen Software House! We will see you again next year!

Announcing the Grand Melee! Tue, 16 Oct 2018 18:34 CEST

Hello, Engineers!

We would like to tell you the tale of the evil Medieval Engineer who became king after his good brother slipped on a banana peel and broke his neck, banished his deceased brother’s children from the realm, doubled taxes across the land (hence the angry barbarians who are in a perpetual state of rebellion against the crown’s new taxes), and banned the mead machine from the Engineers break room.

Anyway, to celebrate the beginning of the evil Medieval Engineer king’s reign, he decided to organize a tournament! The grandest tournament the kingdom had ever seen! A tournament that…

Okay, so none of that actually happened. And for the record, the aforementioned tale of the evil Medieval Engineers king is not official Medieval Engineers lore.

Incorrect Notification About NVIDIA Drivers Fri, 21 Sep 2018 13:04 CEST
NVIDIA recently released a new major graphics driver version 411.63. This change of the major version number is causing notifications in Space Engineers and Medieval Engineers about out of date drivers. This notification is incorrect and can be safely ignored. We will patch the games soon to correct this.

Thanks for your understanding]]>
Update 0.6.4 Patch 3 - Minor Update Tue, 18 Sep 2018 15:01 CEST

Hello, Engineers!
Like last week, we have two things for you: a developer diary, and more bugfixes! In today's developer diary we are joined by Sergey Leonidov, one of the designers on the Medieval Engineers team. We go into an in-depth discussion about the ideas that went into, and the processes behind, the creation of the new combat system.

Additionally, we have a few small changes for you today. The most important one is the fix for the crash to desktop that you have been reporting when placing blocks on the toolbar, or scrolling through the variants. For those technical among you, it was caused by a race condition between the loading thread and the rendering thread.

Medieval history has countless examples of conflict and war. For this reason, combat has always been part of the plan for Medieval Engineers. So for 0.6.4 we have overhauled the combat mechanics entirely to make the combat feel more alive and exciting, and to provide more interesting fights. Additionally, we have overhauled the resource balance, updated the HUD for readability, implemented a new chat system, and many quality of life improvements. There's bound to be something for everyone in this patch!
