The ports have an "output" and "input" mode with different textures, you can change the mode by shift-right clicking the port with a configurator. For some reason, no matter what I do, only the input texture is shown when I use the ctm system. For now I am using default block textures, but CTM textures are much preferred!
Also special facing support. Salination Plants now fully connected - the Controller texture could do with some cleaning up to improve the connected look.
I've made modifications to the original system to allow multi-meta CTM, such as between Dynamic Tanks and Dynamic Valves. This also allows texturing with effectively 5 textures, as opposed to the 47 needed previously
