If you move an object on a design or template that has AI shadows, Photoroom will either:
Regenerate the AI shadows to suit the new position of the object
Leave the AI shadows in their current position.
On the iPhone and iPad version of Photoroom, you can choose whether Photoroom regenerates the AI shadows. For instructions, see Control auto-regeneration of AI backgrounds and AI shadows.
Currently, you can't turn off auto-regeneration of AI shadows on Android or the Web App version of Photoroom.
