Today, Quixel who were purchased by Epic Games back in 2019, just released a free dynamic tree pack for Unreal Engine. More then just a simple collection of scanned trees and foliage objects, this pack contains a full season control system, dynamic wind and support for multiple LODs. This is the first pack in a series and this one focuses on European trees.
Details from the Quixel blog:
Today we’re introducing the long-awaited early access of ‘Megascans Trees’, a brand new asset type unlike any we’ve released before. Far from being ‘just another type of foliage’, our first pack, available on the Unreal Engine Marketplace for free, is the culmination of extensive research, development and iterations on how to capture these complex and beautiful living things.
In order to do justice to the magnificence of trees and create a faithful adaptation of nature, our approach has been a scientific one, relying on botany and deep knowledge of how trees grow, react to light, wind and respond to seasonal changes. The result has been not just a set of assets but also a powerful foliage master material to control seasons and wind.
