This weekend I've been playing around with Megascans, Mixer and SpeedTree and this is the result. Also, this is my first work using Raytracing (I thought I would be worst with my GTX1080, but I'm pretty happy with the result). The scene has been rendered in UE4 and all the light it's dynamic.
All the assets in the scene are Megascans, except one tree for the background where I used a Megascan trunk for the lower part of the tree and then with Speedtree and a Megascang texture I extended the tree and added the branches.
The ground materials made in a quite simple way with Mixer blending some textures and atlases.
