A Change of Seasons
This is a small test scene of a forest set that I have been working on in Unreal. The set is for a much larger environment, but this made it easier to test altogether and kind of fun to show it all.
The seasonal and weather changes are all controlled by a single Parameter Collection that drives a few master materials.
The default Spring/Summer look.
The transition from rainy and wet into a dry Fall look.
The seasonal slider can remove most of the foliage like how this clip starts and then you can start the snow build-up.
Unreal's detailed lighting view.
