## Asset Source

An asset pack and sample scene from the pack (https://assetstore.unity.com/packages/3d/environments/nature-starter-kit-2-52977) were used to create the asset images. Per their FAQ page on their website (http://shapes.hu/faq/), everything in their company store (such as the asset pack) can be used in commercial projects.

The heatmap was generated from the difference between pas_0 and pas_100 to show the range of what would be affected by the filter.
