 Welcome back in this step We're going to take a look at a different way of lighting our environment Which is to use what's called a sky dome light which uses image-based lighting So we take an image and Maya and Arnold take parts of that image generally the bright parts and cast light into the scene using that It's a really good way of creating naturalistic looking scenes Or if you want really cool looking reflections in things like metallic paint or something like that Okay, so let's give this a go. I'm just going to turn that off and Then I want to find and delete my directional light because this new light is pretty much going to do the job that directionals currently doing So that's gone and then we're going to go into Arnold find lights and create a sky dome light There it is by default. It's just kind of lighting everything with this white color Which is fine and sometimes is useful, but it's not the effect that I'm wanting we're going to load in a HDRI image So that it lights things a little bit more naturally in order to do that We're going to click on the little checker pattern next to the color for the light we're going to choose a file and then we're going to click on the file and In our source images folder again if you're using my assets You should have copied this and put it into your own source and we just folder at some point Otherwise feel free to find your own HDRI image. So it's HDRI underscore forest You can see there's a preview of it It actually looks better in the scene than it does there So we'll click on open and just so we can see a little better Let's zoom out a little bit and we'll just rotate around you can see it's just a nice little wooded area It's beautiful and this is now adding lots of light to our scene what I want to do that You can see there's the sun there. I want to rotate that around so that it's located where the window is So I'm going to select my sky dome light turn on my rotate tool and Then I just want to get in nice and close here And I'm just going to press a in one of these views and rotate it around You can see that the scenes updating to reflect that I'm doing this Until the sunlight sort of over there somewhere and hopefully it will cascade through this window now that we've done that We're going to need to start thinking about Previewing it so I've still got my Arnold renderer being previewed up here So I'll just press play to let that start going and as this renders coming through you can see that It's giving a much more natural look to the scene of light cascading through the window falling across the scroll It's pretty nice actually. I'm quite happy with it If however you decide that you're not a fan of certain parts then that's where you can make changes So perhaps you think it's a little bit too bright so you might not the intensity down a little bit So let's try something like 0.6 That does seem to be a little bit nicer And if you wanted to try to get a cleaner set of shadows You could also try upping the samples as this is mostly for preview purposes I'm not going to do that. I think what I'll do at this stage It's just find an angle that I like let it render out and then we will move on to the next step So let's just stop this rendering for a sec find a nice angle. That's kind of nice And we'll just give that a minute to render That's the rendering done then for this particular version of my lighting I think it's come out pretty nicely and it's something that for a different type of project I would maybe try if you wanted to get the lighting to look even more believable You could create some other walls So I just turn that off a second You could put some walls here and walls here and also put a cube on top to stop the light getting in Because it's currently coming in from every angle even if it's darker somewhere else There is still light coming from that So if you really want to experiment with this a little bit and control it So it's only coming in through the window then you can do that or leave some little gaps in other places to Represent like other windows or doors That's going to do it for this step then in the next step, which is going to be the last one where we use a type of light We're going to use what's called an area light and I'm going to use that to cascade in what will look a bit more like Moonlight and try and get some volumetric shadows going on through the window.
