Hey, i have followed your guide, and i have reached the end with inject folder, overlay showing and working and going into file/browse texture assets the mods i have added are showing but in game no textures are being changed.. any help would be great thanks.
Hm. Make sure you are extracting the mod folders and not just dropping the zip in your textures folder.
Try extracting a pack directly into your Textures folder and let me know if that changes anything. I remember SKIM sometimes not liking folders inside Textures.
Sorry if you are doing those things already. It's hard to determine what exactly the problem is when it just doesn't work but if it's opening in game and you have the folders you should be good to go.
Also, just to clarify, you are putting your mods in the inject folder in your Hearthstone folder not the my mods folder right? The difference between SKIF and SKIM is where they look for the injected textures. SKIF looks in my mods so you may still have an injection folder in your my mods if you tried to use it in the past. SKIM(the version you are using) looks in the Hearthstone folder so double check and make sure your mods are extracted to Hearthstone>SK_Res>inject>textures.
If that doesn't help you may have to just try again. Wipe your my mods folder delete the program, reinstall Hearthstone and give it another go. I know it's tedious but the guide your following should be the most compatible for any machine.
Let me know if that doesn't work and I'll try to replicate your problem on my end.
