Objects can be stacked on top of each other. The order of how the objects are stacked are determined by the order of the layers in the layers section. For example, by default the iPads are above the magazines so that an iPad can be placed on a magazine.
For best results, it is recommended to stack iPads on magazine covers and closed magazines on each other (i.e. do not to stack open magazines).
Also to ensure the image looks as realistic as possible, the left-hand side of the top object (the side with the drop shadow) must be completely on the bottom object. For example, the left hand side of an iPad placed on top of a magazine must be placed on on top of the magazine so ensure the shadows are correct. See screenshot below as an example.
To keep the shadows looking realistic, the left side of the iPad is fully on the magazine below.
Please note: If you wish to stack objects that hang off the edge of the table, you may need to adjust the shadows of the top objects. If you see the shadow of the top object cut off like the example below then please follow the following steps.
If the stacked objects are placed close to the edge of the table, you will notice the shadows of the top object get cut off.
1. Expand the folder of the top object or objects. Find the shadows folder highlighted blue.
2. Right click on the layer mask of this layer and click ‘disable layer mask’. The layer mask will have a red X through it.
3. If you no longer want to have objects stacked and only wish to have one object hanging off the edge of the table then you will need to re-enable the layer mask by right clicking on the layer mask and selecting ‘enable layer mask’.
The layer mask has been disabled and now the shadow of the iPad is correct.
