Highly recommend having KKUTS 2.4β at https://ux.getuploader.com/nHaruka_KK/download/152

put the mod in mods/Sideloader Modpack - KK_MaterialEditor and delete all other KKUTS and KKSUTS in that folder

KKUTS 2.4β doesn't work correctly in koikatsu sunshine (and KKSUTS is not enough). So, I don't really know if it going to work correctly in koikatsu sunshine but you can try ¯\_(ツ)_/¯.
