I set a test for myself to see how far I could take Gaea on a random terrain in 20 minutes. This was just to test our internal builds and see how the features held up in real scenarios, but ended up becoming a nice little scene.

See this blog post for a full tutorial on how this terrain was created.

Icelandic scene created with Gaea. Apart from a few small scatter stones, and the immediate foreground objects from Megascans, the entire scene consists of assets created in Gaea.

A top view of the main terrain - created using a displaced plane. The heightmap and color map are 4096x4096.

Rendering component breakdown. The terrain relied heavily on the texture to provide the realism. The base shape remains very simple and "walkable".

The lighter ground texture for the higher slopes.

The darker mud texture for the lower slopes.

The vegetation mask.

Composite texture with ground colors and vegetation.

The final terrain and texture with additional wear and tear.
