Progress Update 7/04/2026
Hello and welcome to another Thrive summer break Progress Update! As our lead programmer is on vacation, we will be providing you with weekly updates on volunteer programming contributions, and things that happen outside of programming.
The main news this week is Multicellular Auto-Evo is steadily advancing. There are now a few mutation strategies that actually add cells to species in a few different patterns. The next step will likely be the creation and placement of new cell types.
There was also some code refactoring and fixing going on for the Multicellular membrane stretching system. One notable thing that you can't (easily) see on a screenshot is that the stretching is dynamically adjusted as cells grow on the body.
Meanwhile, the Development Forums saw discussions on the current state of radiation in the game, and Multicellular Editor mechanics.
Look below for some additional details and we'll see you next week for another vacation Progress Update!
