I have installed AC 4.3, and put it in the AC resourcepacks folder:
At first screenshot you put resourcepack in a ArdacraftModpack folder at the next one you open a ArdacraftDevpack folder…
You simply launched the wrong pack…
If you put resourcepack in a ArdacraftModpack folder you have to launch from the ArdacraftModpack, if you want to play at ArdacraftDevpack you have to move/copy the resourcepack to the Devpack folder
Damn I’m stupid thanks guys
Ye you are.
