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 it just me or is the admin spawn command for the glass wall missing?

im trying this in single player before asking a friend to put them on their server and I'm having issues getting any cosmetic color changes to appear, I tried initially a spray painter before realizing you can do it in the radial menu, or so i thought. The colors aren't changing from default on the foundations from what ive tried so far...Any suggestions?

There doesn't seem a way to change the colour of the chevrons on door frames and doors. Is there a way?

is there a problem with wide pillars? On my dedicated server, you can buy the engram but it does not show up in the workbench. With GCM it is possible to craft them :)

What is going on with the electrical lights? They say they are powered but the activation option is gone. When you click on the inventory it says to place a battery in it. Do they now need batteries? They used to work great with the generators until this Gen 2 crap.
