ArenaLightPorter is a tool designed to seamlessly transfer lighting setups from WWE 2K22 and 2K23 to WWE 2K24. It ports LightObject.jsfbs and other .jsfb files that contain lighting setups (e.g., floor, ceiling). Please note that while it’s an ideal solution for porting lights, other data in these files, such as linked objects (e.g., floor.mdl, mtls), will not be transferred. Once ported, these files will only retain the lighting data, and you won’t be able to manually add the missing data back. This tool is useful for anyone looking to maintain consistent lighting when porting from previous generation games, without the hassle of manual adjustments.
If you encounter any issues while using it, please let me know, as it’s still in the experimental stage.
(Nb: You can port as many jsfbs as you want in the same session)
Update: Added in an Highly Experimental Feature "Port LightGroups". LightGroups are the files used on 2k20 for lighting setup  . there is also lot of lightgroups leftovers from 20 in 22,23,24 files.
