Use the simple shadows action to add a shadow to a 3D object. It’s a good idea to add simple shadows to 3D objects in world effects, to make objects look more realistic.
You can use actions to add common features and techniques to your project in just one or 2 clicks. Learn more about other actions available in Spark AR Studio.
To add a simple shadow to a 3D object:
In the Viewport and Simulator a shadow will be visible under the object.
By default the size of the shadow will reflect the size of the object.
When a shadow is added, a block is added to the Assets panel and instantiated in the scene. In the Scene panel it’s a child of the 3D object you’ve added the simple shadow for. It’s labeled Shadow - [3D object].
The block is made of objects and settings that render, position and size the shadow in relation to the object. It contains:
To edit the shadow, adjust the properties of the block in the Inspector.
Adjust the Position, Scale and Rotation values to position, resize and rotate the shadow.
Set which cameras the shadow is visible in, and whether it’s visible during preview, capture or both.
Min Position and Max Position
Patches representing these properties are connected to the Bounding Box patch in the Patch Editor. As a result the shadow never appears too small or too big for the object.
Change the color of the shadow.
Change how transparent or opaque the shadow appears.
How hard or soft the edge of the shadow appears. When the value is bigger, the edges will be softer.
Make the shadow into a square shape.
Change the vertical position of the shadow.
