Why use HDRI in Blender

When it comes to 3D rendering, lighting is one of the most important factors that can make or break the final result. And while traditional methods of lighting ( such as sun lamps) adding artificial lights to a scene, can work well, there's another option that's becoming increasingly popular - using HDRI environmental textures to light a scene in Blender.

HDRI (High Dynamic Range Imaging) environmental textures are essentially 360-degree images that capture lighting information from the real world, including the intensity and direction of light. During creation camera captures hundreds of photos with different exposure, resulting in an extremally high dynamic range of up to 30 EV during sunny day. When used in 3D software, these textures can be used to create realistic lighting effects that mimic real-world lighting conditions, resulting in more natural and believable renderings.

So, what are some of the advantages of using HDRI environmental textures to light a scene in Blender? Let's take a closer look.

HDRI render example

1. Realistic lighting

As mentioned, HDRI environmental textures capture real-world lighting conditions, which means they can be used to create highly realistic lighting in 3D renderings. This is because the textures capture not only the intensity of light, but also the direction and color of the light, resulting in lighting that looks much more natural and convincing than traditional artificial lighting.

2. Time-saving

Using HDRI environmental textures to light a scene (especially outdoors) can also be a huge time-saver compared to traditional lighting methods. Rather than having to manually place and adjust lights in a scene, simply selecting an appropriate HDRI texture can quickly create a natural-looking lighting setup. Additionally, HDRI textures can be easily switched out, or tweaked allowing for quick and easy experimentation with different lighting and nodes setups.

3. Improved reflection and refraction

HDRI environmental textures also have the added benefit of improving reflections and refractions in 3D renderings. This is because the textures capture the environment around the scene, which is then reflected or refracted in materials within the scene. This can result in much more realistic and believable materials, such as glass or metal, that accurately reflect and refract the environment around them.

4. Versatility

HDRI environmental textures can be used in a wide range of 3D rendering scenarios, from architectural visualizations to product renderings to character animations. This versatility makes them a great choice for any 3D artist looking to create realistic lighting in their work.

In conclusion, using HDRI environmental textures to light a scene in Blender can be a highly effective and efficient way to create realistic and believable 3D renderings. Whether you're a seasoned professional or just starting out in 3D rendering, incorporating HDRI textures into your workflow can help take your work to the next level.

The Royalty-free (RF) license covers all files in HDRI WORKSHOP. This license protects the work so that it allows commercial use without naming the author, but does not allow the resource to be re-sold in the same form.

My name is Paweł Wałasiewicz and I do 3D work as a side job. Over the years I've gathered quite a rich library of HDRI created for my projects and decided to publish them for free on HDRI WORKSHOP and via the Blenderkit plugin. I have all rights to distribute materials on this website.

The HDRIs I made are available to download under Royalty Free license on this site and through the Blenderkit plugin.

The process is quite complicated and requires taking hundreds of photos of the environment at different EVs and several shots of the sun, with an ND4096 (12 stop) filter. The photos are then edited and combined into a panorama. Finally, I add the sun to the file with exposure correction for the ND filter.

Yes, I offer 3d modeling, especially for the real estate market. You can check details on this website.

Creating HDRI is very time-consuming and requires travel to an interesting location. I use all money raised by the donations to maintain the server and create new Royalty-Free HDRI.
