![Visual explanation of the 3 textures that make up elements of the terrain. An image on top shows a crop of the scene from the OP and highlights one part of the cliff. Its 3 textures are displayed below along with descriptions.

Shading mimicking global illumination reflected from golden grass is manually painted onto it] "shadow texture. this appears when a shadow is cast on it, or when the mask reveals it"](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:2d2kzr2qck4mxownc2j7std4/bafkreicwxe566x2oqn6nofp4nvo4yuomcqx7vlxp2rdwr4koucgysjvsky)
