You used to be able to plug an HDRI image into the background node, and into the world output. Is this a new "feature" of 2. Your node setup uses an Image Texture instead of an Environment Texture node.

The correct node setup is shown below.

I have an object with an hdr for the background. What do I do in Cycles to render the background with my object? There are a few pieces to make this work. Note that there are a few differences on how this works in 2. In the world section, set the surface to Background and the Color to use Environment Texture. Once the image is loaded enable Scene World in the viewport shading. Otherwise blender will use an HDR image that is "built in". Think of it a as a huge sphere that completely surrounds the scene.

Note that the Background can only be displayed in perspective viewit will not be on orthogonal view. The HDRi not only becomes the background for the scene, but is also used to light the scene. Every pixel of the HDR image contributes to the lighting of the scene. That is why the results of lighting wiht an image resemble the real world, where light acts in very complex ways.

The intensity of the illumination of the scene can be controlled by making the image brighter or darker with the Strength value on the world settings. The rendered image will be lit bythe HDR image and use that same image as the background of your scene. If you want to use the HDRi to light the scene, but want a transparent background to be composited later with the background, or want to blur the HDR or maybe replace the background all together, then enable film transparent and enable the Environment output for the render layers, and use it as a different element in the compositor.

In the World section of the Shader Editor add a Texture Coordinate node and a Mapping node to control the placement of the Environment texture.

By changing the rotation on the mapping node you can place the HDR where you need it. Sign up to join this community. The best answers are voted up and rise to the top. How can I render an object with an hdr background? Ask Question.How often, have you found yourself randomly places lamps in different locations of your scene hoping your render will miraculously come out super realistic? It would make sense to add grey to the model and then a little shine… tell me, was your render realistic?

I am guessing no! Do you see where I am coming from? Using cycles as opposed to the Internal engine does come with some differences in the set up of materials to your model. Cycles use a different rendering and lighting algorithm that produces more physically accurate and realistic looking results, whereas the internal engine uses point lighting… look at the image below for example. Notice how with the internal render engine, the difference between the light and dark areas are very abrupt.

To further illustrate this, imagine being in your room and you have one window where the light comes in. In reality you do not get one side of the object lit up while the other side is pitch black. You will notice that in this case the HDR image that is our background does, in fact, consist of an urbanisation with blue sky and clouds… essentially the very same things that light bounces off. In order to make use of the background HDRI map which is effectively our light source we now need to add materials to our models.

In the above video, we have a sphere and a cube in our scene, both of which I wanted to make look metallic… one shiny and the other not so much. When rendering with cycles for the first time, you will notice an instant grainy effect followed by an eventual improvement.

This is the algorithm calculating real-life lighting conditions until if feels it has got it right. However, depending on the settings, the render can still be a little grainy and can do with some tweaking to get that crisp, sharp and realistic finish. High Dynamic Range Imagining is a technique used to create images that have a similar luminance to that experienced through the human eye.

Simply put, an HDR image is a closer representation to what we normally experience compared to an ordinary picture taken from a digital camera. This is made possible because with HDR, you are combining several of the same image but at different exposures and light intensity, resulting in amazing quality.

Nodes are essentially blocks with a choice of settings that can be interconnected or routed together in order to create a variety of complex material textures and appearances. So I felt it would be easier to compare the differences between the two engines in the form of a bullet list. Well interns of render time, cycles do take far longer as there are far more calculations to be made.

The same is valid for Blender 2. We delete with X our default point light as well. Your scene will ideally be different, since the assumption is that you will let the HDRI's realistic lighting endow one of your creations of more artistic value than this example scene.

This may take a while, depending on the size of the HDRI file. Depending on the characteristics of the HDRI, the scene may now appear sometimes absurdly over- or underexposed.

This is because all of aifosDesign's HDRIs have been meticulously calibrated to actual light intensity with EV 9 as the absolute reference pointin contrast to the arbitrary normalization prevalent in other HDRIs, and Blender's camera has implicit exposure settings equivalent to EV 9, which may produce a darker or lighter image than intended.

When you think that the exposure is balanced enough for your artistic vision, switch back to [Filmic]and optionally further fine-tune the exposure, until you are satisfied with the results. All aifosDesign's HDRIs are delivered with a recommended value for balancing the Exposure value to eye-pleasing levels — found in the attached Read me file or on the product page — however, this is only intended as a starting point for further experimentation into what your artistic desires want to achieve with regards to lighting your scene.

The major perk of the absolute light intensity calibration paradigm, is that all of aifosDesign's HDRIs can accurately be used for simulated physical camera workflows i.

EV-dependent scenesas well as being more reliable when used interchangeably in conjunction with light objects of static intensity e. If you are using a scene-referred workflow e. However, it is easy enough to restore in any image manipulation software that can handle linear images, such as GIMP 2.

Delete the lamp so we are only using HDR lighting, then add a plane so we can see the shadows cast from the cube by the HDRI light source.

Change to rendered view mode to check the lighting. Regardless, make sure you set something like at least samples. To solve this firefly issue, go back to World tab, Settings and change Importance Sampling to or You can further adjust the brightness of your HDR and the lighting it gives off by using the Strength variable.

Clamping the maximum light level will effectively cut off the super bright parts of the sun, and reduce any remaining fireflies. A value of is probably good, but just adjust to suit your situation. Cutting this number down too low will somewhat negate the point of HDRs in the first place!

You can also try upping the importance sampling even further. This will smooth out the bounced light rays. There are some more complex things we can get into with Nodes for different diffuse and reflection maps, but this was just a quick starting point that requires the minimum of fuss.
