Now that I have a much better understanding of Unreal4, I wanted to see how much I can follow a concept. Considering I don't have much "natural" work in my portfolio, this was the perfect subject matter. The complexity of the landscape was quite overwhelming initially (muds, puddles and displacement) but the result was quite good.
Again, I didn't want to create much from scratch and most of the assets are from Epic themselves via the Paragon pack they released for free!
I used Speedtree for the specific tree creation I wanted and used the fantastic (and sometimes finicky) "Smart Spline Generator" for Ivys
