Terrain and Aesthetics - Finishing Touches

For the surroundings of the scene, we wanted to add terrain for the track to stand on to improve the aesthetics. This was made using Unity's built-in terrain tool.

The scene with added terrain.

We used textures that I had previously made for personal projects. These were originally created by taking pictures of grass and rock which were then cropped into squares. The resulting pictures were then made seamless in GIMP, using the built in "make seamless" function.

The used grass and rock textures.

Normal maps were automatically created for these textures using the website: http://cpetry.github.io/NormalMap-Online/

The normal maps that were auto generated from the website.

We also used a previously created texture to create grass clusters. This texture was made using the following pictures of grass straws.

Cut out grass straws from pictures of grass.

The grass straws in the above picture were copied, scaled, rotated and skewed, which created the following sprite.

Using the built-in terrain tool in unity, billboards with this texture was used to decorate the terrain and the grass and rock textures were used to paint the terrain.
