This week’s update is introducing an important feature to rotors and pistons. Just like pistons have been doing for a while, rotors now also lock by default at around 100m/s. We've also added the ability to manually choose the speed at which pistons and rotors lock as well a safety lock override checkbox. A new audio distance (echo) system has been implemented into our engine this week which means the volume of sound effects will change depending on your distance from the sound source. Some changes regarding ownership when building in space master have been made. When building with creative mode tools enabled in space master, the ownership of any block that you place will automatically be assigned to you. New rifle sounds have been added which will help you to identify the different variants. Lastly, we are releasing a new texture modding tool which is designed to help modders create game-ready textures.
