Notice!

The asset includes a Unity package for Unity 3D (native) and a zipped version (exchange) of the project folder. This 3D package is designed to be used with the Unity game engine, as the shaders, materials, and scenes are created within the engine. Therefore, you will not benefit from them in FBX format, except for the modular FBX meshes and the textures, if you intend to use them for something else.

If you don't use Unity, textures and materials are not connected to the FBX and left blank!

Description

Rocky Hills Environment - Mega Pack is a 3D art package with simple and fast foliage shader solutions for artists. Includes third-party tools.
High-quality, semi-realistic 3D environment art package for games and 3D applications version 4.0. Little to no photo source material as most textures are made using Substance Designer or hand-painted. Assets are well optimized as 4k atlases make it light for GPU and memory while prefabs contain LOD levels.

Compatibility

This pack is compatible with Unity (SRP: URP + HDRP) 2021.2.3f1 or higher. This pack does not support the Standard/Built-in RP.
The main pipeline used is the "Universal Render Pipeline" containing one HDRP conversion package inside. Switching to the High definition render pipeline is relatively easy and now works out of the box.

Tested in Unity versions: 2020.1.3f1, 2020.3.23f1, 2021.1.1f1, 2021.2.3f1 and 2022.3.1f1

- The vegetation contains and works with the third-party tools Custom tree importer (CTI) which is compatible with Advanced Foliage Shader. The custom tree importer shaders provide realistic-looking wind and foliage with minimum performance impact so there is a good possibility of use on lower-end platforms.
- (TFS - Toby foliage shader) is a new lightweight, fast and simple shader for vegetation made in the Amplify Shader editor. Works in URP and HDRP. *Read more in the "releases" tab.

• Grass Foliage shader

(Custom Amplify shader for grass): Physically-based lighting with translucency, simple wind, includes color variation, vertex Ao, and distance depth fade supports mesh with custom normals. Wind and other parameters can be controlled globally through the (upcoming) wind script.

• Tree bark and leaf shader

(Custom Amplify shader for trees): Physically-based lighting with translucency, simple branch bending, wind, and leaf fluttering, supports trees with custom normals on leaves, including color variation and vertex Ao. Wind and other parameters can be controlled globally through the (upcoming) wind script.

(At the moment the wind is controlled directly through the shader so you will have to match both values of the bark and leaves together.)
