The container overlay texture menu can be used to view the current overlay texture of a custom container, replace it, or generate a template texture for it. If you haven't chosen an overlay texture yet, this menu should look like this:

But if you did choose an overlay texture, it should look like this instead:

Buttons

Back

The Back button will take you back to the container edit menu.

Save to file

The Save to file button will save the current overlay texture of the custom container to the file Custom Item Sets/containers/CONTAINER NAME/overlay.png. After the file was saved, it should automatically be opened in your default image editor program. This can be useful if you would like to make small changes to the overlay texture. (This button is only visible if the current container has an overlay texture.) This button is very useful in combination with the Choose saved file as overlay texture button.

Generate template

The Generate template button will create a template overlay texture for the custom container at the file Custom Item Sets/containers/CONTAINER NAME/template.png. After generating the template, it should automatically be opened in your default image editor program. The template is a very simple 'example' overlay texture that shows you where the edges of the custom container and its slots are, which should make it easy for you to edit. This button is very useful in combination with the Choose template file as overlay texture button.

Choose overlay texture...

The Choose overlay texture... button will open the file chooser menu, where you can choose the overlay texture for the custom container. While this is possible, it is usually more convenient to use the Choose template file as overlay button or the Choose saved file as overlay texture button.

Choose template file as overlay texture

Chooses the image stored at the template file location (Custom Item Sets/container/CONTAINER NAME/template.png) as the overlay texture of the container. This button is useful in combination with the Generate template button:

  1. Click Generate template, which should open the template image in your default image editor
  2. Edit the template texture until you're happy with it
  3. Save the template texture in your image editor
  4. Click Choose template file as overlay texture, which should choose the modified template texture as your overlay texture.

Choose saved file as overlay texture

Chooses the image stored at the saved file location (Custom Item Sets/container/CONTAINER NAME/overlay.png) as the overlay texture of the container. This button is useful in combination with the Save to file button:

  1. Click Save to file, which should open the previous overlay texture in your default image editor
  2. Edit the overlay texture until you're happy with it
  3. Save the overlay texture in your image editor
  4. Click Choose saved file as overlay texture, which should choose the modified overlay texture as your new overlay texture.

Delete template file

Deletes the template file (Custom Item Sets/container/CONTAINER NAME/template.png). This is just a convenient button to avoid the need for you to travel to the template file in your file system and delete it manually. Deleting the template file is needed when you want to generate a new template file because the Generate template button will not work if a template texture already exists (to prevent you from accidentally deleting all of your image editing work).
