HDRI-Hubs main goal is to provide you with super high resolution hdri images and architectural textures.Often textures you find in the internet are way too small for really close up work, so we like to produce them in this outstanding quality. Most of our textures are at least 4096x4096px large or even bigger and the hdri environments are around 10240x5120px. On custom request many of the skies can be reproduced at even larger resolution.

HDRI Haven is the premier website for free HDRI downloads and officially linked with two sites we have mentioned before, Texture Haven and 3D Model Haven both of which are a magnificent resource for the digital artist.
HDRI Haven is the home of a vast collection of panoramic images available at resolutions starting at 1k rising to an enormous 24k and all available under the CC0 license, which means they are free to use for any purpose even commercially.
Well, thanks to 3D Motion Designer Noah Witchell, you can. Noah has made available seven free HDRI bundles containing HDRI images and preview images in jpg format so you can easily see what the file contains.
ProductionCrate has released an incredible bundle of 100 space and atmosphere HDRIs for you to use in your 3D digital art and VFX. 10 of these are available to download for free today, and only require you to sign up for a free ProductionCrate account.
While the process of creating these can be a laborious technical obstacle, the end result is an asset that can be added to any 3D scene instantly. This is why we created these space HDRI images, simulating an accurate appearance of the Earth from space for you to download now!
The 16K resolution of these space HDRI images provides an unparalleled level of detail with minimal impact on performance. Thanks to the high resolution of this environment map, you can zoom in up close to every cloud scattered in the sky with little loss of visual quality. The 360 degrees of content, combined with the 16K resolution, makes this the definitive space environment that offers your camera unlimited freedom of movement. Tilt up, pan left, zoom in, and witness an awe-inspiring view of Earth from space.
If you need assets to populate your space scene with, ProductionCrate has a collection of free 3D spaceship models for you to explore. Additionally, our library of assets hosts astronauts, aliens, robots, asteroids, and other 3D models that are easy to download, set up and render.
This collection of 10 HDRI images are from the main library at HDRI-skies.com, and are the highest-resolution backgrounds we have available. These are all at least 15000x7500px and cover a wide range of lighting/cloud options from dawn to dusk.
These additional 24 backgrounds also come from HDRI-skies.com and are at least 14000x7000px with a diverse array of lighting conditions and lighting scenarios. There is a "download all" option at the bottom of the table, but please note the full package contains several GB of data.
Five HDRI backgrounds are installed automatically with ProWalker GPU, which can be accessed from the dropdown menu in the Background Settings dialog. ProWalker GPU users are also entitled to over 40 additional HDRI images, which can be downloaded here
HDRI Skies.com offers a large collection of commercial HDRI backgrounds. Free with limited resolution, and paid commercial packages at higher resolutions if needed. This is the best option we know of for natural sky/background images with few man-made objects in the scenes.
Use HDRI Haven's site to download some interesting HDR images for free, or you can use some of the ones available in UE4 that work well with the HDRI Backdrop Actor. Use the Content Browser's View Options to enable Show Engine Content and Show Plugin Content to display Cubemap Assets available for use. UE4 includes some by default that are stored in the DatasmithContent Content/Textures folder.
Not all HDR images are created equal and may require their own custom geometry to project onto. In the Editor, UE4 provides several backdrop meshes to choose from, in addition to the HDR images provided.
Sets the intensity of the embedded Sky Light and how emissive the backdrop HDR image is. Higher values result in brighter ambient lighting being samples from the HDR image (cd/m2). Note that the physical lighting units are measured in cd/m2, like the Sky Light or Emissive Materials. Sun and Sky sources have that range in the thousands of units, which it does hand-in-hand with physical cameras where the Exposure Value (EV) are in the range of EV100:14 (see the "Sunny 16" rule). However, with the HDRI Backdrop asset, it is not required to use physically correct values, but you may need to set the EV to something significantly lower than the EV100:14. It's also worth noting that some HDR images range from 0 to 5.0 or greater than 5 cd/m2 while others are ranging from 0 to 100K units. This means that when you swap HDR images, there may be a noticeable difference in brightness changing.
The HDR image is fed into and driven by a Sky Light. The content of the HDR image will greatly affect the brightness of the scene. The HDRI Backdrop asset doesn't attempt to perform normalizations of the pixel values in the HDR image to provide a stable intensity regardless of its content. This means that when you switch between different HDR images, you will need to adjust the Intensity since this is not handled automatically. However, this may be added in a future release.
Introduction A light probe imageis an omnidirectional, high dynamicrange image that records the incident illumination conditions at aparticular point in space. Such images were used in the paper Rendering Synthetic Objects into RealScenes: Bridging Traditional and Image-Based Graphics with GlobalIllumination and High Dynamic Range Photography at SIGGRAPH 98 toilluminate synthetic objects with measurements of real light, and later in a SIGGRAPH 2000 paper toilluminate real-world people and objects. Two of our animations, Rendering with Natural Light and Fiat Lux demonstrated the use of image-based lighting. The commercial product LightWave 3D v6 was the first to supportimage-based lighting in 1999 and the technique is now commonly supported; see below for links to some sample renderings madeusing our probe images. Some of these images were assembled fromhigh-dynamic-range panoramas, others were acquired by taking one ortwo high dynamic range images of a mirrored ball (see Reflection Mapping).RADIANCE Image Format and Viewing on UnixLight Probeimages are measurements of light in the real world, and thus are highdyanmic range, with pixel values ranging from thousandths to hundreds of thousands.Because of this, these images are provided in the RADIANCE Synthetic ImagingSystem .hdr image format (Described in Greg Ward's "RealPixels" article in Graphics Gems II.) They can be viewed on anX11 display using RADIANCE's ximage program and/or converted tofloating point data using the "pvalue -df -H -h" program from theRADIANCE package. RADIANCE images also use the more traditional butsomewhat ambiguous .pic filename extension, so feel free torename any of the .hdr images to .pic if your softwarerequires this.Viewing and Editing HDR ImagesThe images may also be viewed using USC ICT's programHDR Shop.Raw Floating-Point Image DataThe raw floating-point format images are 4-byte single precision, big-endian, withinterleaved color planes. There is now also a directory with little-endian versions of these float images (whichare useful if you're using a PC rather than an SGI, for example). Takenote of the image dimensions so that you can load them correctly. Wehave also developed a very simple floating-point version of thePortable Pixmap .ppm format (.pfm for Portable Floatmap) which we willsupport shortly, along with the floating-point versions of the TIFFformat.Making Your Own Light ProbesIfyou're interested in creating your own high dynamic range images, theHDRShop packagedeveloped at the USC Institute for Creative Technologies is nowavailable. One of the easiest ways to create a light probe image isto acquire a high dynamic range image of a mirrored ball; othertechniques involve stitching multiple images together (such as withPanorama Tools or RealViz's Stitcher), or using a scanning panoramic camera such as theones available from Panoscan or Spheron.Light Probe Images 2ff7e9595c
