Drag and drop 20 HDRI worlds into your scene, ready to go with God Rays and everything! It's very customizable and you can add your own HDRIs as well.

Each Blueprint has a directional light (sun), two visible HDRI skyboxes (one for Lumen, one for Path Tracing), a sky light, an exponential fog component, and a post process volume component all in one Blueprint.


One of the key features of HDRI Plus is that each one has a sun manually aligned and locked to the HDRI, so as you rotate the HDRI, the sun follows perfectly along!


Another feature is that you can easily change the HDRI, Sun, Sky, Fog and Post Process volume settings all from one details panel of the Blueprint.


God Rays can easily be turned on or off, and adjusting them is also a breeze.

This plugin also works with Path Tracing (unlike HDRI Backdrop plugin).


I've also created a similar default sky. With this blueprint, you have a directional light(sun), Sky, Sky atmosphere, Volumetric Clouds, Exponential Height Fog and Post Process Volume all in one Blueprint. In the details panel you can control all of the most important settings.


The Background

I made this plug in because I use HDRis in a lot of my projects, and the existing plugins for HDRI were not good enough for us. I needed to find a way to make HDRIs work with Path Tracing, so I solved that problem and kept going!

I realized to get the most out of lumen, you need to have a directional light and it needed to be manually placed in the same location as the sun in the HDRI. So i found a way to offset the sun to match, and then quickly rotate the whole world together!


Then I thought, I always forget how to make God Rays work, so I found a way to easily incorporate that into this plugin, so all you have to do is search God Rays and you have all the sliders you need.


From there I added just about every feature I use again and again, from Path Tracing Samples, to Reflection type, so that with one Blueprint, I can control the entire look of my scene.


Overall, HDRI Plus is an excellent plugin for Unreal Engine 5 that can help you create stunning and realistic lighting for your projects. Whether you are working in Virtual Production, game development, architectural visualization, or any other type of project, HDRI Plus can help you take your lighting and background to the next level.

I have tested this plugin on 5.1.1 and it works great, older versions do not work.
