Years ago, I made the graphics for the Tacx Trainer Software Virtual Reality (including tools and shaders).
But after about 8 years, the first levels started to feel a bit outdated, so I got the opportunity to revamp the Mediteranian/Italy levels.
The main restriction was that the road-structure had to remain exactly the same.
But we also didn’t want the levels to suddenly become a lot more demanding (hardware-wise).
I made a lot of new vegetation (grass, plants, trees), and new water-, terrain- and vegetation-shaders among other things.
Improved Terrain UV-mapping
As part of improving these levels, I also created a terrain shader that reduces the vertical UV-stretching that is typical for standard heightmap-based terrains:
