SpriteShapes not displaying for WebGl

I am using the 2D project template. I have created a little program using the Sprite Shapes and am moving them around.
When I press Play, the objects show up in the Game view. But when I Build and Run (or publish) as a WebGL build, they don;t show up at all. (Normal sprites will display, just not SpriteShapes).
The SpriteShapes are simple rectangles with a plain colour.

Figured it out!

SpriteShapes by themselves won’t show up in builds. To use them, one needs to create a ‘Sprite Shape Profile’ object (which I had not done, hence the failure), and set it up so that each part of the sprite shape will have different sprites associated with it.


An alternative is to use the Sprite Creator to make some default sprites.
