Early Access Patch Version: 0.6.17.6112 - April 1st, 2021

A message from the developers

Hi engineers,
With the coming of April, we are about to enter the rhythm of medium / large scale content development, and a new round of difficulties, and an intensive development schedule. It will take a lot of time, but we will forecast the content of the upcoming patch earlier to facilitate you to plan and prepare in advance. For example - the quick copy of the sorters is on its way. Let's see the update log today:

Features

Added system framework of item drop/pick up
Optimized the Assembler GPU Rendering cost by adding the LOD1 and LOD2 to rendering detail levels
Optimized the models of logistics drones and vessels and the rendering costs on GPU

Changes

You won't lose your items due to "Inventory is full" anymore. Instead, they will fall on the ground or float in the space!

Bug fixes

Fixed a bug where mecha walking may be interrupted when pressing S from the perspective of God in the Construction Mode
Fixed the bug where the customized celestial bodies' names may not be updated in the production statistics panel
Fixed a bug where a facility may be built in the wrong place because of failure in the calculating of building placement distance

Early Access Patch Version: 0.6.17.5972 - March 19th, 2021

A message from the developers

Hi Engineers!
Spring is coming! Icarus can't feel warm or cold, but we human beings can still be cold at spring. The Chinese old saying ask people to keep warm so that everyone can be healthier in the summer. Have a try!
We also brought you some new features and fixes today. Let’s take a look!

Features

Now you can customize the names of celestial bodies. You can either rename them on thumbnail in the lower left corner, or on and the information panel on the right side of the planetary view / star map interface.
Added the celestial body operation interface in the star map. Now you can view the celestial bodies easier, and you can decide to turn on/off the space labels of the celestial bodies.
Added the heading indicator line of your target celestial body. You can open the heading indicator line after you find the target celestial body.

Changes

Optimized the logic of takeoff / landing / acceleration / deceleration of Logistics Vessel to make it faster and in line with scientific principles after upgrades.
Modified English translation of some item and technical descriptions.

Balance

Hydrogen fuel rod should have higher combustion efficiency. Increased the energy value of Hydrogen Fuel Rod: 40MJ - > 50MJ
Adjusted the energy consumption of Logistics Vessel: when the sailing speed is upgraded to more than 3000m/s, no additional energy consumption will be increased according to the maximum sailing speed

Bug fixes

Fixed the bug where the rocket could not catch up to the node around some large-mass black holes due to the Dyson spherical node's capture range is not large enough.
Fixed bugs where the game menu will pop up directly when pressing ESC in dismantle mode and upgrade mode.

Early Access Patch Version: 0.6.17.5932 - March 12th, 2021

A message from the developers

Hi Engineers!
Today is the tree planting day in China. Although we cut down a lot of trees in the game, please be eco-friendly in reality ;). We heard your voice of the quick copy of the Sorters, Blueprints, etc. Don't worry, they are on their way - as big fans of factory games, we understand your needs!

Features

The Mass Upgrade / Dismantle function is now available! You are now able to define the scope of batch upgrades/demolitions in the same way as laying foundations. Please notice the red mark in the screenshot above.
LOD1 and LOD2 are added to the rendering to optimize the GPU Rendering cost of the Smelter.

Changes

Remade the model, texture, and VFX of Thermal Power Station, and the interface position for Sorter is fine-tuned.
Remade the model, texture, and VFX of Mini Fusion Power Station, and the interface position for Sorter is fine-tuned.

Bugfix

Fixed the bug where the stored liquid may be mixed, when the liquid stored in the vertical direction with different kinds of liquid in each Storage Tank.

Early Access Patch Version: 0.6.17.5831 - March 5th, 2021

Related Game Announcement

Hi engineers,
We were just astonished to find that the power generation and power consumption of the facilities remained unchanged after a 'quick upgrade'. It is a bug and we are going to fix it soon.
We're sorry to inform that a decline in the electric power supply should be expected after the bug fix, and it may result in large-scale blackouts. Please understand that Centrebrain executes no half measures. So, Engineers! Please prepare your power supply plan and develop the power grid in advance to overcome the upcoming Centrebrain's firmware update.
We will also be adding a function for you to see how the savedata is adjusted after the game version is updated. Thank you for understand and support!

A message from the developers

Hi Engineers!
CentreBrain is ready for the bug fixes!

Bugfix

Fixed the bug where the facility power consumption was not upgraded after a 'quick upgrading'.
Fixed the bug where the facility animations were not upgraded after a 'quick upgrading'.
Added a function of 'Savedata Modification' log. You will be able to look up how your savedata was adjusted after the game updates. We added it In order to prevent the similar situation in the future and reduce some impact of facility data adjustment.

To rephrase the issue that was fixed here, if you used the 'quick upgrade' feature to upgrade an Assembler or Sorter prior to this patch, it did not properly adjust the power requirement to the newly upgraded version. This patch fixes that issue, and will therefor result in any Assembler or Sorter upgraded in that manner, to cost you more power. This could impact your powergrid loads.

Early Access Patch Version: 0.6.17.5827 - March 4th, 2021

A message from the developers

Hi Engineers!
Here comes our first update in March. And, an important functional update is also coming soon!

Features

From now on, the savedata will also save its creator's ID. The players will be able to see the savedata creator's ID in the right upper corner of the game.
Improved some UI interactive SFX.

Changes

Data reduction of Dyson shell. The length of archive data generated by Dyson shell is reduced by 50% ~ 60%, and the save/load time is reduced by 20% ~ 30%.
Data reduction of Sorters and Assemblers.
The research materials won't be returned immediately after the research list is suspended. This change is made to avoid the loss of items caused by the logic of "No item will be returned for fractions of a count".
The scene at the end of the prologue is improved.
Now you can storage/pick fluid items manually and check the information of fluid items.
Optimized the description of some items and technologies.

Bugfix

Fixed the bug where huge amounts of Mini-suns and Storages may make your planet flicker too much.
Fixed the bug where the first frame of the game is incorrect by modifing the loading process.
Fixed the bug where sometimes the mecha may fall into the land after skipping the prologue.
Fixed the bug in calculating the quantity of items when holding Ctrl to operate items in Fractionator.

A Message From The Developers

Dear Engineers,
How’s your galaxy factory going? It has been a week since the launching of Dyson Sphere Program. We’re so glad that Dyson Sphere Program can be liked by such a lot of players, and didn't expect it to reach 350,000 sold copies in one week! It's such a surprise that both encouraged us and pressure us. At the moment, the team is still busy in the game development and debugging to answer the support questions we have received from every single individual, and to make the game have less problems and more fun.
Your expectation on Dyson Sphere Program's potential was provided to us by the feedback and suggestions. Don't worry, most of the expectations are already in our roadmap. But Rome wasn't built in A day, neither the 'Combat', 'Assembly Space Platform' or 'Workshops'.
Today we are going to tell 'what we are going to done before Chinese New Year' (the holidays will begin at 11th February). Most of them are the burning problems from your feedback. Let's take a look:

What we are going to done before 11th February?

Quick Upgrade: You will be able to upgrade some of the buildings and conveyors by directly build (cover/overlap/displace) the higher grade facilities on the lower grade facilities, instead of demolish the lower grade one in advance.
Keybinding: It's a very important function for many of you, engineers. We will finish it before 11th February.
Framework of logistics management system: A basic management framework will be setup to the logistics system. Of course, it will be still 'basic' at February that may only bring 'basic' logistic solution for you, such as the farthest transportation distance and the quantity requirement of delivering goods. The logistic system will be fleshed with the progress of game development in the future.
A more detailed Game Development Roadmap will be published after Chinese New Year holidays. Tons of contents you are looking forward are included in it - such as "Combats", "Assembly Space Platform", "Workshops", etc.

At the end of the letter, from the bottom of our heart, thank you!!!

Feature

Smart Warp: From now on, your mecha will not miss or hit on the planet - It will decelerate and turn off the warp engine automatically as it approaches to a planet in warp. Thanks to the latest warp firmware!

Bug Fix

Fixed the bug where sometimes the vessels can't catch up with the planets with a fast revolution.
Fixed the bug where sometimes the rockets can't catch up with the Dyson Sphere with a fast rotation.
Fixed the bug where sometimes the mecha walked with the wrong VisualFX and SoundFX.
Fixed the accumulator UI layout so that the words don't overlap

Game Setting

Now you have more choices on Max FPS Options, such as 30fps, 144fps, etc.

Early Access Patch Version: 0.6.15.5655

A message from the Developers:
Hi engineers,
Thanks to all of your efforts, the amount of Dyson Sphere is increasing in the galaxy while the bugs are vanishing one after another. Your support are encouraging us to move forward. Thank you!

Improved

You will find that the UI is running more smoothly in manual research, technology tree and research queue than before. The UI efficiency has been optimized 0.5ms/frame.

Bug Fixes

Fixed a bug where the distance may not judged correctly while constructing a logistic station.

Early Access Patch Version: 0.6.15.5651

A message from the Developers

We wonder that if our dear engineers still stay up late after the CentreBrain have release the clock from real life yesterday. Engineers, remember to take care of yourselves, improve their immunity and eat good, rest good.

A Prompt: if you can't launch the game with a "not responding" error under Windows 10 system, we suggest to check Window Update to get the latest Windows 10 version. It is known that Windows 10 1709 version may not be able to run Unity engine games.

Feature

The advisor is bringing 2 new guidelines for you.
Add a readable XML file for game option saving. This file can solve the game crash caused by an error on initial game options while launch the game.
Add a path override file which can be used to solve the problem that some players are not able to launch the game due to the system disk directory.

(If you can't start the game, try the following steps: Find [Game installation path / config/ path.txt ], fill in 'archive' in [path.txt], save and exit it. and then start the game again.)

Changed

Some texture and map have been modified in order to adapt to certain resolutions

Balanced

The probability of Deuterium Fractionation has been increased from 0.5% to 1% (only apply to the new facilities build after this patch)
Increase the generating capacity of Dyson swarm from 30kW/Solar Sail to 36kW/Solar Sail

Early Access Patch Version: 0.6.15.5642

A message from the Developers

Hey Engineers!
How is everything going? A reminder before today's update note: It's ok for you to sneak off for a travel, but a long-distance travel without enough fuel and warp flight may not be a good idea. (The exhausted Icarus will float in the universe for a while to recover its power.) Anyway, out team will look into the early stage travel and see what we can do for it.

User Interface

Now the local time in real life is displayed in Dyson Sphere Program - Don't be confused by the 'CentreBrain'!
