High Dynamic Range Imagery, or HDRI, is a popular tool used in 3D environments and rendering to add realistic lighting and reflections to a scene. A Nebula HDRI is a type of HDRI that specifically captures the lighting and reflections of a nebula, or a cloud of dust and gas in space. These types of HDRIs can be used to create realistic space scenes or to add a sci-fi touch to any 3D environment.
In this post, I have listed some of the free Nebula HDRI images that you can use for your 3D environments and renderings.

Free Nebula HDRI Images
Understand that some of these images are not hdri; rather, they are 360 images, but they can still be used as hdri, and also make sure to check the license of these hdris, as some of these might not have a free commercial license. I have already checked and found that most of these are CC licensed, but some might not be.
If you’re a 3D artist looking for high-quality HDRIs to use in your 3D environments, look no further than the Nebula HDRI pack. This pack includes three free HDRI images that are ideal for creating immersive, sci-fi 3D environments.
Nebula HDRI nanopack Free
The Nebula HDRI Nanopack Free is a collection of five decent-resolution HDRIs that are perfect for creating detailed, amazing sci-fi 3D environments. These images feature stunning nebulas and some celestial objects, making them perfect for creating science fiction or space-themed environments.
Nebula HDRI nanoPack Free
The Nebula HDRI nanoPack Free is another great collection of five HDRI images from the same author that is similar to the previous one but also great for creating some unique immersive 3D environments. These images feature a variety of different nebulas, as well as other celestial objects such as stars and galaxies.
The Skydome HDRI is another great HDRI pack of 3 that is perfect for creating 3D environments. These images feature beautiful, detailed space-themed skies that are perfect for creating realistic 3D spaces and sci-fi environments.
This is a paid product, but its creator offers a free HDR version that is limited to 2K resolution. If you like this, I highly recommend you buy it, as you will get a commercial license for using it in your projects.
Blender Space Nebula Node Group
The Blender Space Nebula Node Group is a Blender nodes group that allow you to easily create realistic nebulas in your 3D scenes. This is perfect for 3D artists who want to add some extra realism to their 3D environments but also want the power of proceduralism.
This comes from Mark North, who is big in the blender community and often creates many premium products for blender artists.
FREE SCI-FI SPACE HDRI 360
Finally, the FREE SCI-FI SPACE HDRI 360 is a very vibrant and colorful HDRI; give it a try if you’re looking for nebula and gas clouds, as well as beautiful stars.
These images feature stunning nebulas and other objects and stars, making them perfect for creating science fiction or space-themed environments.
This can make a small-budget project look like a big sci-fi space movie.
FREE SCI-FI SPACE HDRI
Also from the same creator, this is also an HDRI image, but with more of a vibrant green and blue than a purple, so if you are a fan of this color scheme or like the nebulas, then definitely check this out.
