Plus, claiming Copyright on a CC-BY license item is in of itself illegal.
SCPF literally stands for “Special Containment Procedures Foundation” so claiming that making a “SCPF” game on Roblox is copying another Developer is asinine - if anything both parties involved are making a work based on an open source game / set of ideas.
If it was a developer of a game outside of Roblox, say Croteam for instance, and they wanted to be “more rude” because I was making a clone of their game on Roblox, they would have every right to.
This discussion honestly got a lot more heated than it needed to be, and there’s no basis for the people accusing OP of copying since you can’t copy an open-sourced idea.
Back to the topic at hand, @bxnani
If you’re going for dark lighting, set everything to a sub 40 value in the RGB properties. You could also try and make the lighting have a dark blue or purple (I find it to be good for full moon maps.) But in general, values with no color (40,40,40), (25, 25, 25) etc. look best for really dark maps.
For Voxel lighting, you can currently mimic it somewhat ( the contrast / color parts of it) by adding a ColorCorrection Effect and increasing the contrast & brightness values.
