Did you get the texture files with them? If so these files go here...... FeralHeart>Media>Textures> and drop the files here. Or if you didn't get the files with the pack add them manually, according to their mats. Also try turning all the files into .png files. Or if they are .png try a .jpg, If this works I enjoyed helping you! Like always, have a good day, any good luck with the ishue, hope you get that fixed Hun ^^
