Open the ". minecraft" folder of your game, click the Version folder, select the latest version, there is a. jar compressed file, extract it to another folder and open it
Open it and then enter assets\minecraft\textures
Copy all the folders in it to the<current workspace folder>\src\main\resources\assets\<workspace name>\textures, and rename "block" to "blocks", "item" to "items", and "entity" to "entities" (it is recommended to merge folders)
*Note: There are still many folders of different entities in the "entities" folder. Because MCreator cannot recognize the folders in the resource, it is necessary to copy the files from the folder and paste them into the entities when using them!
"Painting", "misc" files can be directly copied to "textures".
Finally, (re-)Open the Resources tab of the workspace to see it.
