2. First, we open a packing bag. Then open a picture material. We need to select this picture material first, and then copy it.

3. Next, let's go back to the packaging bag interface. We copy a layer and then create a new blank layer.

4. We select a blank layer, click the "filter" above, find the "vanishing point" and click it.

5, into the vanishing point processing interface, we draw a selection box, and then hold down the Ctrl key and drag the border with the mouse to cover the border on the outline.

6. Next, press Ctrl+V, paste the picture you just copied, drag it to the picture with the mouse, and finally click OK.

7. Finally, we can change the mode to positive overlay.
