Okay well is there any chance some one could post there SubstanceCore.dll and The other Substance.Dll from the new devkit? no matter what i cant obtain these files. (Giant EDIT : Fixed the issue if you have third party plugins on UE4 normal they get pushed over to arkdevkit plugins and it throws an error i found a copy of Substance Designer ue4 plugin in ark dev kit deleted it bam works fine now.)
