Tech Tree Update

This month we have added the tech tree which will give you the choice of how you unlock your blueprints, this has also led to a huge update on item crafting recipes, tiers and the loot you will find in airdrops and heli/bradley crates.

03 December 2020
In November 2017 I implemented Workbench experimenting which allowed the player to use scrap to gain a random unknown blueprint. Since this time we've added nearly an extra 130 items which has made random experimenting both costly and frustrating. Say goodbye to experimentation and say hello to Tech Trees. Each level of workbench has its own tech tree composed of all of the items within its tech level. This new system allows you to see the entire tree of items and allows you to unlock them in a linear fashion, choosing paths and allowing you to specialize. This should make it much more comfortable for a new player to unlock weapons and armor instead of having to pray to the RNG gods to find a SAP in a crate. Keep in mind you can still find and research items you find in the world using the Research table as normal, this hasn't changed. But if you're not having any luck you can at least make progress and know that you are working towards the items of your desire. We're not expecting the balance to be perfect so expect changes going forward, we'll be reading feedback and adjusting accordingly for January patch which will be a mandatory blueprint wipe across all servers.
This month after implementing our own and considering hundreds if not thousands of common community balance concerns we went ahead and made over 300 balance changes, touching nearly every item. Here are some of the most notable change:
  • Majority of crafting times reduced
  • Reduced all Electrical crafting costs
  • Majority of electrical items now stackable
  • Hazmat suit now uses condition
  • Road sign armor crafting cost reduced
  • Increased Rocket Launcher deploy time
  • Smoke grenade now craftable and researchable
  • Removed blueprint drops from barrels and crates
  • Complete reblance of torso underarmor clothing
  • Large medkit now provides small amount of instant health and cheaper to craft
  • Greatly reduced the amount of dehydration when consuming anti-radiation pills
  • Reduced Medical Syringe crafting time
  • Reinforced window bars now have glass
We'll be keeping an eye surrounding these changes and hopefully see a slight shift in the meta. The full extent of these changes can be found within the changelog at the bottom of this page or viewed here.
Rust's airdrop has been unchanged since it's inception in 2013, the airdrop has become iconic over the years, yet unchanged. It was long overdue an art update. Tom Butters has given the airdrop a makeover bringing its visuals up to date with Rust 2020 standards. This includes actually attaching the parachute to the airdrop with wires. Wow. The loot tables for the air drop have been completely rewritten from scratch and work by rolling for specific categories of items several times. You're now guaranteed to find at least two pieces of decent armor and one very good, or two decent weapons. No more Wood armor, longswords, landmines, or stone spears. P.s. We will be addressing the Helicopter and Bradley loot in the near future but note that for now we have greatly reduced the chance that you will find an aforementioned crate with crappy loot such as a single CCTV camera or Laptop.
As promised last month, we have now once again enabled procedural horse and motorboat spawns around the world but at a slightly lower rate than before. Additionally, we have lowered the purchase cost of the motorboat and rideable horses.
I've spent quite some time this month on figuring out why our builds were slowing down a lot over time when using Unity's Asset Database v2. What we had noticed was that importing assets that had changed takes a lot longer on v2 than on v1. The solution is naturally to avoid reimports, which isn't exactly trivial when you have to use asset processing at build time for client and server builds or rely on parameters that should update automatically on the prefabs whenever needed so there's no danger we forget to update / commit those changes and accidentally break everything. All of this was amplified by the fact that EditorUtility.SetDirty no longer seems to work right for prefabs. You now have to call SavePrefabAsset or SavePrefabAsAsset depending on which prefab edit mode you're using. Of course the docs don't make any of this clear, but after figuring it out our build times improved a whopping 25% from this change alone.
We had to temporarily disable Steam Networking on official servers due to a race condition that could corrupt the connection state and lead to all sorts of inexplicable side effects. Thankfully it was an easy fix once we noticed that it was caused by an async disconnect callback, so we will once again enable Steam Networking on all official servers this month. While I was digging around I also added support for maxreceivetime to Steam Networking, which improves client performance. I also disabled some features we didn't need that were adding some additional packet overhead on the server.
There's now over 20,000 Movember Moustaches floating around Rust. Together with a donation that Facepunch made, it means that together we raised ~$80k, making us together one of the single biggest donors to Movember UK this year - thank you! if you want a laugh, you can see some of our efforts to grow moustaches here during November too. It's not too late to donate to or learn about Movember either, which is working to make a difference in men's mental health & suicide prevention, prostate cancer and testicular cancer.
Rust turns 7 this month and we’ll be celebrating for one day only on 11th December with a birthday cake and hat item. In the near future, we plan to talk more about how the last year has gone and what we learned as well as some information about how Rust has performed.
The kayak model has now been updated, along with improvements to the viewmodel animations. After the paddle initially went in-game, Paul spotted some issues and gave some good feedback on area's that hadn't translated from concept to model. This included proportions, details, and the fact the world model didn't really stand up from a 1st person perspective. We wanted to rectify these issues so Tom went back & made the necessary changes to the model. As the proportions had changed, the animation also needed to be updated to account for the new grip position. I took the opportunity to correct some issues raised on the viewmodel posing as well: Going forward we're hoping for stronger collaboration between concept/model & animation. This includes Paul giving me a very rough block out mesh that I can rig & get straight in-game for an initial prototype. From there we will be much better placed to see where details are needed, what proportions will work best, & viewmodel posing. Tom can move forward with a final model knowing how it will work in-game.
We released an update for Rust+ earlier this month with a redesigned user interface, notification history, the ability to promote team members to leader, and server logos! Team leaders can now promote other team members to leader by tapping on a player's avatar on the Team chat tab and clicking the Promote button. You do not need to be playing on the server to do this so no more problems if your team leader forgets to change it! We have also added server logo images as a new configuration that server owners will need to set up. Simply set the server.logoimage convar to your logo URL and you're good to go. The logos are circular (on a squared image) and, for best results, should fit into this guide image: Make sure to check for updates in the settings menu by swiping from the left to open the server switcher and then tapping on the gear icon!
We've added a few new useful console commands this month for cinematic content creators:

DOF Target Mode

A new 'target' mode has been added to the debug camera's depth of field setting. This mode allows DOF focus distance to be locked onto a specified entity or object, either during demo playback or live gameplay.
Use the command dof_mode 2 to switch to targeted focus mode whilst in debug camera view. To set a focus target, use one of the following methods:
  • dof_focus_lookingat - Sets the focus target to the entity which the camera is looking at.
  • dof_focus_target [entityID] - Sets the focus target to a specified entity ID. You can find entity IDs during demo playback by using ent_find_radius [number] which prints out a list of entity names + IDs in a defined radius near the camera's position.

Parented Dolly Movement

When parenting the debug camera to an entity, the previous behaviour for dollying, aka moving the camera closer or further away (as seen above), was done by using the mouse scroll wheel. We noticed a lot of creators preferred binding mouse scrolling to perform other tasks such as adjusting focus distance, so instead we added convars to allow manually binding keys for dollying the camera in or out of a subject. Use the following commands to set a key bind for parented camera dollying:
  • bind [key] +debugcamera_dollyforward
  • bind [key] +debugcamera_dollyback

Demo HUD - Target Readouts

The demo playback HUD has been updated to include two new readouts:
  • Camera parent target - Name and ID of the entity which the camera is currently parented to (if any) as indicated by a chain-link icon.
  • DOF focus target - Name and ID of the entity which the camera's DOF is currently targeting (if any) as indicated by a target icon. This only appears when DOF is set to target mode.

NVG in Demos

During demo playback you can now use the command togglenvg 1/0 to enable night vision goggle effects whilst in debug camera view. This should prove useful for creators wanting to utilise the existing NVG effects in their own custom camera angles.
We're aware of the issues, in some cases, where the in-game list only populates a handful of servers. We've discovered this is a problem with the current Steam Beta. We are working with Valve to ensure a proper fix is handled. In the meantime, if you are experiencing these problems, please opt out of the Steam Beta build and it should repopulate the list. Steam Client settings >> account >> Beta programs (opt out of it)
We'll be releasing a mandatory patch on December 17th at 19:00 GMT / 14:00 EST to enable this year Christmas festivities.
