As a small example, Andesite was called stone_andesite.png in 1.12 and andesite.png in 1.13.
is there a list where I can see which textures have changed from which name to which name? I want to update a texturepack.
Unzip the Minecraft jar under% Appdata> minecraft> versions> the version name
It works like every zip.
Go to the folder and find the Assets folder.
There you will find the folder structure and file name
I know that it works, I actually meant a list of where the old and the new name is. Now I have created an Excel spreadsheet that contains the old and new names. Then I wrote a Python script that copies the old textures with a new name to another folder.
