Flex Splines
Break the boundaries of vanilla construction! Build longer, tighter, and more complex logistics networks that snake through your factory with total freedom. This mod adds lenght to vanilla buildings and adds new flex buildings that can be in strange forms.
Longer conveyors, pipes, tracks, hypertubes and powerlines.
Unlock unique building shapes via Hub milestones.
Curvature freedom for compact, high-density layouts.
Defy standard gravity and placement restrictions.
💡 Bright Hologram Solution
If your belt holograms are too bright, adjust the luminance of the secondary color in your settings:
(Thanks to Sevetamryn for the fix!)
Honest note: Your factory doesn't have to be a box. With Flex Splines, it can be a work of art!
