Wouter Weynants has finally released his plugin for Unreal that allows users to produce stunning results on Gumroad.

Hemisphere Skies lets its users set up photorealistic lighting and skies in real-time. This new system is based on real-life time-lapse recordings in HDR. "It uses true to life Physical Lighting Values based on the data from a solar intensity logger," wrote the developer.

Features:

• Editor Integration. Full sequencer support and intuitive UI
• EV100 Mode. Use accurate cd/m2 and lux values to light your scene
• Dynamic Lighting. Fully dynamic with a custom SkyLight-based solution

The developer has also submitted his toolkit to the Unreal Engine Marketplace, so it should be available there too. You can learn more and get the tool for $15+ here.
