Folded map effect in Storyline
Fortunately Storyline (or PowerPoint if you want to use a map directly in Studio) lets you do that within 15 minutes.
Folded map effect is easy and straightforward achievable in these 3 short steps:
1. Insert a screenshot of a map.
2. Add an outline and a shadow.
3. Create few shapes (there are 6 rectangles in my case) and add a gradient as a fill.
Et voila! Here's how it looks like.
It probably needs some more detailed work with the fills, but is good enough as a basis for recreating.
