Hi everyone, Captain Marek here. It's been a while since our last diary, but we haven't been idle (unlike some of your trains, as you will see later). We've been busy working on new features and improvements, which I will go over in today's diary. And I am happy to announce that all of them will be…
Improvements The selected game speed now stays highlighted while paused, and the pause button toggles. A save that fails because the drive is full now reports the free space instead of a generic error. Simulation determinism Fixed cargo depots and shipyards losing their blocked ocean area in ship…
Improvements Transports and mini-zippers now highlight the ports of the entities they connect to (including their suggested product icons). The in-game hub UI now loads images and files from a CDN, making loading faster. The in-game downloader now verifies the integrity of every downloaded file…
Simulation determinism All simulation math now runs on a pure-integer arithmetic, so results are bit-identical across CPU vendors and machines. Fixed vehicle path-finding that could finish on different ticks on different machines. Fixed ship path-finding behaving differently depending on whether…
Added new 3D models for T1/T2 Electrolyzers. Optimized truck buffer balancing when storages or dumping designations are cut off from trucks, which caused FPS drops at high sim speeds (over 10x faster in those cases). Fixed incorrect layout of height 4 ramp entrances. Fixed trains planning…
New content and improvements Modular ramps can now go up to height 4, being able to go above train tracks. Vehicles now approach ramps slightly faster. Trade dock cargo is now included in the global search. Increased the number of switchbacks allowed in a single train path from 16 to 32. Trains no…
v0.8.6b Fixed a possible game freeze in highlight rendering and restored the tower highlight on area hover that was temporarily disabled because of it. Fixed transport highlights that could get stuck or attach to the wrong transport right after an upgrade. Fixed an error when splitting a transport…
Improved belt graphics to make the belt direction more visible. Temporarily disabled the tower highlight when hovering its area to prevent a game freeze/crash. Fixed train station modules disappearing when zoomed out too far. Fixed train track overlays rendering incorrectly against blueprint…
Hello, Captains! Update 4.2 has just landed, and it’s a big one: full COI Hub integration directly in the game, modular ramps, a host of new train features, and major performance improvements. We’ve also put together a new trailer highlighting the key features, while this post takes a closer look…
Welcome everyone to today's edition of Captain's diary. I am Captain Marek and today I will be talking about some serious performance improvements we've done over the past few months. Are you ready for 20x faster products rendering? Before that, I have an important announcement. Update 4.2 is…
