It is possible that the models @Dulki previewed are just visual replacement for the current machines.
Maybe each of the 4 blocks composing each machines will have a new visual in order to have them all stand out better.
But I do hope that the devs are working on something more than that.
It seems very possible that we’re not gonna have the machines in groups of 4 blocks anymore, and instead, we’d have lots of individual stations for each aspects of crafting (which, when you think about it, is how pretty much every other crafting game works…).
I would hope that spark and power would have a better looking way to be attributed to machines. The current system would simply look terrible with these new 3D models. It’s already an eye-sore IMO, and as I’ve said in a previous suggestion thread, in a way, it forces the player to design his workshop pretty much like everyone else.
I tried to have a nice looking workshop with hidden powercoils in the past.
But as time went on, I felt the need to optimize it further to have max power for each machine :
I’ve recently reworked my base to have something optimized and still nice to look at.

but I could not figure out a way to also have the individual machine blocks look nice too.
Problem is… now, it’s the exact same type of machine placement everyone does.

Bottom-line, if the devs manage with their overall to allow us to have an optimized workshop that looks pretty and where each machine block is presented in the best way possible, good job.
