Rocky Hills Environment – Mega Pack (SRP) v5.0.1b (15 Nov 2025) (Latest version)
“Sharing is caring”
Description
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
○ 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

⚑ Limitations
???? TTFE is designed to work with instancing; static batching is not supported.
