Interesting ideas. I agree that having a single slider doesn’t work so well with shells. If we put shells in the external organelles section then they are binary, there is only one thickness rather than a slider. I’m open to options on this. One possibility is to have a 2D selector, with the rigidity on the x axis (from soft -\> normal -\> double -\> cell wall (both chitin and cellulose together)) and then have shells on the y axis (silica at the top -\> none -\> calcium carbonate at the bottom). That way you can have any kind of membrane and then put any thickness of shell around it. Cell wall + thick shell would be the ultimate defensive strategy. ![](https://thrivedevforum-uploads.b-cdn.net/original/1X/9815bc4855d434f37b251f67316030a24f29facf.png) --- _[View the full topic](https://forum.revolutionarygamesstudio.com/t/membranes-characteristics/556)._
