The Quixel shared a recording of their recent livestream on snowy projects. 

The guide prepared by Quixel's Jonathan Holmes, Jack McKelvie, and Joseph Downer will tell you more about Unreal Engine's powerful Blueprint system. The most important aspect is the generation of a seamless snowy path on a terrain using Unreal and Megascans.

For those of you who missed the news, Epic Games has recently revealed the acquisition of Quixel at Unreal Academy London. All Quixel Megascans became free for all artists using Unreal Engine. Quixel’s primary operations remained based in Sweden, and over 100 employees across six countries joined the Epic Games team. This means that you can start creating similar projects in no time.
