I have been working on this blueprint tool set to make it easier for me to setup some physically based lighting in UE4 and I thought I will share it with the community, maybe it could be useful to people.
- Light meter blueprint
- Point, Spot, and Rectangular light blueprints with additional Luminance(cd/m2) unit added and some other features.
- Sky blueprint with easy Sky dome setup, and some handy other features to setup PBL fast and easy.
I have made an extensive tutorial on the tools and how to use them so make sure to watch that first. In the tutorial I have some information about how it works and how its setup and I also show some things I discovered along the way. Here is the video link.
And you can download the tools here:
And here are some relighted scenes made with these tools. No fill lights or any other trickery is used. For daylight scene only the sky and the sun is used, or just the sky if it’s overcast scene. And for interiors no additional fill lights were needed, for the sci-fi hallway scene I used static emmissive set to some physically based high values together with my Lights BP tools set where the light sources are. I used GPU Lightmass for building the lights.
Let me know if this is useful to you, and any feedback on the tools is welcome.
