Mod Summary

CKF:SF takes the building experience of CKFR structure mods and mixes it in with a grounded Sci Fi art style. With over 75 parts included in the release build with many more planned in future content updates, combined with the enhanced remastered CKF snap system. Users will be able to build to the limits of their imagination.

Enhanced snap system;
Walls now snap side to side, as do the roofs and even around corners, leading to a more enjoyable building experience, greater structural integrity and more ways for you to realise your epic builds.

All the parts in CKF:SF are full colour adjustable colour adjustable with multiple static mesh variants within the parts to provide even more customisation. All parts are designed to fall within the performance optimisation of vanilla parts, with models and materials made to be within vanilla spec.

This mod will be registered onto the Beacon App shortly after release, to allow users to to more easily add this mods items to spawn beacons on their servers.

*This mod contains building and construction parts, there are currently no decor items within the mod. If you wish to decorate your builds, there is a wide variety of existing decor mods available on the steam workshop such Eco Decor and RP decor. The decor items used in some of the user submitted build images that may be displayed on this mod page above will be found within those decor mods.

is there a way to get the lights to turn on automatically at sundown? my lights don't shut off and on, is there a setting for that or just how they are?

Stairs don't snap downward from walls?!? 1/3rd walls feel incomplete with no stairs and the other stairs not snapping to them. Missing greenhouse effect feels like author doesn't even play the game.

Are you planned to upload this mod on ASA ?

If you're still updating and adding more content to this mod, can you add a Behemoth Rolling Gate? 4 Wide, 5 high. Or 5 Wide, and 6 Tall.
A giant size like that would be perfect for the Aircraft Carriers I make :)
