Mastering Lighting in Unreal Engine | From Simple Sources to Complex HDRI and Volumetric Effects | 3

If you want to mastering lighting in Unreal Engine - watch this series!
In the third video - we start by exploring four basic light sources, followed by two complex ones with multiple components. Key topics include manipulating directional light, which affects the entire scene regardless of position, and adjusting light intensity and color to suit specific needs.
The tutorial also covers advanced techniques like controlling sun rotation via keyboard shortcuts and adjusting source angles for desired blur effects in reflections. We address how to manage reflections using specular parameters and temperature settings for color adjustments. Additionally, the video illustrates the impact of volumetric lighting, showcasing how to create stunning light shaft occlusions and density settings for a more dramatic effect.
We further explore point lights, highlighting their role in illuminating dark spaces or mimicking light bulbs, and rectangular lights, ideal for spotlighting specific areas. The tutorial stresses the importance of understanding and adjusting light source parameters like attenuation radius, source radius, and source length for desired lighting effects.
Towards the end, the focus shifts to HDRI backdrops, detailing how to integrate them effectively into scenes. We discuss the challenges of rate tracing, the necessity of adjusting project settings, and the use of cube maps for enhanced realism.
The video culminates in a detailed guide on using the Sun and Sky instrument in Unreal Engine. This powerful tool allows for accurate lighting based on geographical location and time, demonstrating its versatility through various examples. The tutorial emphasizes the importance of adjusting light intensity, global illumination values, and skylight settings for achieving the perfect balance between sunlight and ambient light.

Overall, this video is an essential resource for anyone looking to master lighting in Unreal Engine, providing valuable insights and practical tips for both interior and exterior scene illumination.

This is very good. But there is one thing I miss very much: lighting flickering! :) Your pictures are very clean - my ones are flashing like hundreds of lamps :) Could you make a video about lighting flickering issues and how to remove them? Thank you very much.
