Scroll down to find and select " VrayHDRI". It’ll show up a Material browser dialogue.
Switch ON the " GI Environment(skylight) override".
In the " Renderer" tab, scroll down to " Environment" section. See how the scene naturally turns dark at one point and brighter at other point. With this we can see the different radiance values stored in the HDRI. Lets see an example of this in Adobe Photoshop CS3.Ĭheck out the slider at the left bottom of the screen. An HDR image is created from a set of photographs of the same scene taken with different exposure levels of the camera. An HDRI is a set of techniques that allows a higher range of radiances or luminances between light and dark areas of a scene than normal digital imaging. Its called " Snowfield".įor the people who would be new to HDRIs HDRI stands for High Dynamic Range Imaging. I, for this example will be using the one below. These renders are mainly to check the anti-aliasing in the scene. Now, as we saw the renders above, they look dull which is obvious as they don’t have any lighting done nor any textures put up. This will give us an output something like this:Īlways remember, that when we take a test output in Vray, with no lights put up, always keep the "Default Lights" option in "Global Switches" rolldown ON, else the output will be completely black, as there are no lights at all!. We can get a good and fast render for previewing purposes with these settings: Now go to the "Renderer" tab and do the settings as below. Open your Render setting dialogue box(shortcut key F10) and in the "Common" tab, scroll down to "Assign Renderer" and choose "Vray Adv.1.5 RC3". Here, I’ll be using a Castle scene for the example, that I have modelled, textured and lighted up.Īnd here’s what we’ll be trying to acquire.įirstly, lets try to get decent render settings in the scene wihout any texture maps or environments.
#Portalight and hdri in vray 3ds max how to#
In this tutorial, we’ll work out to know how to do a decent lighting using HDRIs using Vray 1.5 RC3 Renderer in 3Ds Max 9. WARNING: Do you get a unreal proportioned backgrounds? You are probably using low/bad quality HDRI maps.Hello, this is Shashank Sharma, or better known as shashanks18 on 3DM3. – I bought 5 hdri here… these files are excellent!!!
In this video I will use one of its files to give you an example of the HDRI power: (I bought many hdri from Peter: I’m so satisfied) You just need 1 light! – Use only good HDRIs: : I love Peter Gutrie Hdri! With HDRI you don’t need to tune more parameters in order to according all these  features because it’s all embedded in the HDRI file. HDRI is the easiest way to light a scene getting a perfect light, HDRI is perfect to accord: Sun light does not decay so everything appear flatter.īut there’s a solution! The way to achieve a rich light, with a lots of shades is HDRI. In a different way the exteriors are often lighted by the sun, this light condition is simpler but the problem is the flat lighting. In interior renders the light decay is clear, this is why interior renders have more shades and they look nicer than exteriors. The big difference between interior and exterior renders is the light: precisely the way as the light is spreaded in the scene.
