Rocky Hills Environment - Mega Pack

High-quality, semi-stylized environment art package for games and 3D applications. Most textures are hand-crafted in Substance Designer or digitally painted — minimal photo-sourced material ensures full artistic control.

○ Compatibility

Primary Pipeline: Universal Render Pipeline (URP) with HDRP conversion assets included.

Free Upgrade: Purchase includes the Built-in Render Pipeline version: Rocky Hills Environment - Mega Pack (SRP)

○ Product Overview

The pack is split into two foliage systems with distinct shaders:

□ (CTI - Custom Tree Importer shader)

Works with the third-party Custom Tree Importer tool (compatible with Advanced Foliage Shader).
Delivers realistic wind animation and foliage shading with minimal performance cost

□ TTFE - The Toby Foliage Engine (Free Version Included)

Lightweight, high-performance single-pivot vegetation system built in Amplify Shader Editor.
Simulates multi-pivot behavior (similar to Pivot Painter) using innovative techniques.
Global Controller Gizmo lets you tweak wind strength, direction, and seasonal changes in real time.
Seamless mesh integration — no conversion or setup required.

* This pack only includes the free version, which has limitations! Unleash the potential of the fully featured version here: The Toby Foliage Engine

○ Features

Terrain detail painting support
PBR materials with optimized LOD meshes
Summer, Fall, and Winter seasons for all assets
1,000+ prefabs
Unique cliff meshes
Seasonal ground splat textures
Variety of tiled ground materials (all seasons)
20 particle effects
7 example scenes
18 Amplify shaders (16 fully editable):

Shader:

Detailed Map Coverage Snow - Animated sparkles + tessellation
Detailed Map Coverage Moss - Dry/healthy color variants + tessellation
Simple Snow Triplanar - Efficient seasonal overlay
Ice Shader
Running Water + Reflections
Custom Standard (Tessellation)
TTFE Foliage Shaders - Non-editable in free version

⚑ Limitations

🞫 TTFE is designed to work with instancing; static batching is not supported.

🞫 Free TTFE version: Shaders are locked (node functions removed) — upgrade for full Amplify editing.

🞫 Shader Model 4.5+ required (Desktop / High-End Mobile).

🞫 Mobile support: Example scenes are performance-intensive — used mostly for testing.

⚑ Shader bug with the light direction node only in the built-in version of the TTFE shaders. For further details, please refer to the Discussion Thread.

Release Notes

*Nontice!

This version contains a few changes that may not be backward-compatible with your current project, so the update may not work well with older versions. Make sure you make a backup first!

Bigger cosmetic changes, improved textures and materials, new scenes, and more.
Added new player camera script and improved scene demo scripts.
Replace the (TFS) shaders with (TTFE - Light) shaders.
Terrain detail painting is now supported.
Better integration with the terrain engine
Optimized and reworked most shaders. Includes more functionality and better performance.
New shader features like tri-planar coverage for moss and snow have been added.
Updated the water shader, now works with the planar reflection script.

Updates and improvements V 4.1

Compatible with Unity 2022.3.1f1 (LTS) or higher
Updated new and improved foliage shaders with custom deferred translucency
Updated all shaders to work with DirectX shader model 4.5
Updated CTI textures, better translucency, and fuzzy-looking trees
Trees now have crossfading billboards
Minor aesthetic updates

Updates and improvements V 4.0

• Better integration with the terrain engine

• Complete cosmetic change, remade textures

• Reduced file size and optimized textures

• Updated Amplify shaders (fixed bugs and screen NaNs)

• Added new "Toby foliage shaders" (TFS)

- Grass Foliage shader

(Custom Amplify shader for grass): Physically-based lighting with translucency and simple wind, including 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 support 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.)

• New (TFS) demo scene

• Interactable demo scene with UI from HDRP.
