Join Brian Bradley for an in-depth discussion in this video Working with the V-Ray dome light, part of V-Ray 3.0 for 3ds Max Essential Training.
- Having taken a look at one V-Ray specific skylighting tool, that being the GI Environment option, we're going to look in this video at the V-Ray dome light which, in my honest opinion, offers not only the greatest flexibility but ultimately the greatest quality when it comes to creating a skylight in V-Ray. To create a dome light, we will need to follow some pretty familiar 3DS Max creation steps in that we need to come into the lighting section of the command panels create tab. And after accessing the V-Ray light section from the drop down, go ahead and select the V-Ray light button.
Now, we could create our V-Ray light and then switch it over to acting as a dome light in the scene. But, as I like to save mouse clicks wherever possible, I am going to instead access the type drop down and switch the option to dome before I go ahead and create the light, which I can then do very quickly by means of a single left mouse click in the top viewport. Instantly, we have a V-Ray dome light set up and ready to work with. Of course, don't forget to right-click in order to exit out of creation mode.
With the V-Ray dome light, just as it is with 3DS Max's native skylight, the actual positioning of the gizmo that we have created here won't make any difference at all to lighting in the scene. Unlike the 3DS Max skylight, however, the orientation or rotation of the V-Ray dome light gizmo can make a difference. To demonstrate that, let's take a render of our camera view and then store that in our frame buffer history. One thing you will have hopefully noticed as we took that render there is the fact that the V-Ray dome light doesn't need GI enabled in order to create a skylight effect.
What we are seeing here is the result of a hemispherical dome of direct light instead. With the dome light selected then, let's hit the E key, to enable Max's rotate tool and make quite a change to either the light's x- or y-axis rotation. Something like a 90-degree rotation should work well. We can then take another render and make a comparison between the two images that we have. And as you can see, the rotation we've made has made a big difference to the final lighting solution.
One thing well worth noting here is the fact that only rotation on the x and y axes will make a difference. Rotating about the zed axis even with a HDRi applied to our light, won't alter the lighting solution that we're getting. In terms of controls, because the V-Ray dome light is just an operating mode of the V-Ray light itself, if we come to the modified tab, we get access to pretty much all of the same controls and parameters that we have already taken a look at in regard to both the plane and sphere light options.
That having been said, there are a couple of extra controls available on the dome light that we will probably want to take note of. For instance, the texture option here which is available when we use the V-Ray plane light becomes a little more significant in that should we want to use a high dynamic range image in our lighting set up, then this is where we would place the actual image file. We also have, if I just scroll down the roll outs here, these dome light options that give us the ability to switch from the default hemispherical behavior to a full spherical version should we require it.
We also have options for working photon emission for both global illumination and any caustic effects that we may have in our scene. The V-Ray dome light as you can see then, provides us with an almost complete lighting solution in and of itself. I say almost complete because you will notice in our initial render here, that the underside of objects in the scene don't actually receive any light. Which of course isn't surprising given that using the hemispherical version we have no light traveling in an upward direction.
And even if we switch to full spherical and did have light traveling that way, it would of course, be blocked by the ground geometry. Another thing we would have to admit in terms of quality settings in the scene is that there is a lot of noise currently showing up in our render. To fix this, we could work with the sampling sub-dibs option where higher values will produce more samples which should in turn produce a less noisy image. In our quality control chapter a little later on though, we will see that this isn't always a required step when we want to get cleaner renders from V-Ray whilst making use of its dome light option.
