changedHello everyone, Today we’re reopening experimental with several changes, but the most important one of them is an optimization we’ve done a refactor of how we handle Spline Collision in-game, so now Conveyor Belts, Pipelines and Hypertubes should only have collision when a player is near them, this should also result in memory optimizations for bigger saves that use a lot of them.
changedThis could potentially have unintended effects in both Singleplayer and Multiplayer/Dedicated Server so we wanted to release this in Experimental first to see if there’s anything we need to address before these changes come to the default version
changedRefactored Spline Collision This affects Conveyor Belts, Pipelines and Hypertubes
fixedFixed “Let’s see what’s out there” achievement did not work when playing in languages other than English
changedFix for a specific crash when loading saves that contain Conveyor Belts built by blueprint auto-connect during 1.1 Experimental when it was not working correctly and have not been resaved since
fixedFixed null pointer crash when logging discrepancy between picked up items on client and server

Hi Pioneers!

Hello everyone, Today we’re reopening experimental with several changes, but the most important one of them is an optimization we’ve done a refactor of how we handle Spline Collision in-game, so now Conveyor Belts, Pipelines and Hypertubes should only have collision when a player is near them, this should also result in memory optimizations for bigger saves that use a lot of them.

This could potentially have unintended effects in both Singleplayer and Multiplayer/Dedicated Server so we wanted to release this in Experimental first to see if there’s anything we need to address before these changes come to the default version

If you notice any weird behaviour after this update, please let us know over at our QA Site https://questions.satisfactorygame.com/ We read your feedback every day

See you all again soon <3
