Whether you’re creating a moody deep-forest scene or need lush green grass and sunsets, these 13 FREE HDRIs have what you’re looking for.
Since Turbosquid is now part of the Shutterstock family, it’s time we started giving away some FREE tools for CG artists, as well.
One of my favorite things about working in CG is how you can take your surroundings and things you come across in life, and find interesting ways to include them in your work. Capturing HDRI light-maps with a 360 camera is a perfect example of this. Anytime you’re out in the world and just happen to notice interesting patterns of light, or a certain mood and tone created by your surroundings, just pull out a 360 camera and capture it to use with your renders. This is exactly how we created these FREE forest HDRIs.
One thing that I’ve noticed when going through HDRI sites is that they often shy away from trees and objects with the potential to create a lot of movement. This is because to make an effective HDRI, you have to stitch and merge together multiple exposures of the same place, and if the wind blows surrounding the grass or trees, you get some “ghosting.”
However, to me, all HDRIs should really be used for is reflections and lighting. If you have a scene where the HDRI is so visible and central to the scene that a bit of ghosting or artifacting throws everything off, you’re probably relying a little too heavily on your HDRI.
A selection of some of the different looks included.
As a result, I’ve always found it hard to find good HDRI of forests. Especially deep forest looks. This is what set me on a mission to go and grab some of my own to give away here.
So, enjoy these FREE HDRIs that I captured on a few different hikes and camping trips.

What Is an HDRI?
One of my personal favorite looks from this pack.
So, if you aren’t familiar with CG or VFX, you might not be familiar with the concept of an HDRI, especially as it relates to computer-generated design. So, what exactly is an HDRI?
HDRI stands for High Dynamic Range Image, which can really mean a lot of things in different contexts. But, in this context, it refers to a raw 360 degree image that contains an extreme amount of light detail from the high end of the spectrum all the way to the low end.
A perfect HDRI can go all the way from almost black to fully blown out.
To make an HDRI, you take different exposures of a scene at various shutter speeds so as to capture the highest amount of light information possible. Then, when you take that information into your CG software of choice, you add this environment map to a dome light or sphere, and allow it to light your scene.
When done correctly, this will provide extremely realistic tonality and shadows on your subject.

When creating photo-real renders, in almost every case, you’re going to have a more realistic starting place if you begin the process with an HDRI. With photo-realism, the name of the game is introducing enough of that natural randomness that happens when light starts to bounce all over the place. Even if you augment your scenes with a lot of CG lights, you’ll still be helping yourself out a lot if you start out with a HDRI base layer.
How to Use HDRIs
How to use an HDRI in Blender
It’s generally pretty straight forward, but the process is different for all software and renderers (such as Redshift, Octane, Cycles, etc.).
Regardless of your 3D package of choice, HDRIs are going to make your renders better in almost every case. They just add that intangible bit of realism to every scene.

So, get out there and make some moody outdoor renders. I’ve been having a lot of fun playing around with this pack, and I hope you do, too.
