I'm trying to modify HMF_ARM_CTHk .dds files and I keep getting this error message for the 6 mods I've tested: System format exception: different image format, original is DXT5, new is DXT1. ME3Explorer texplorer saltTexture2d oneimage to rule them all - string image file name, string archivedir ME3Explorer texplorer texploere add biggest image tool strip menu item click - object send, event args e I 'think' what needs to be done is the .dds files have opened up and then re-saved in the correct DTX (5 vs 1) format in PSP or another compatible program? Any advice on how to go about t his would be great. Thanks.
