- The sun and sky settings in InfraWorks add a whole new dimension to the realism you can achieve with your model. They also have practical purposes too, for performing light and shadow studies or for orienting and arranging parts of your model. Let's explore how to adjust the sun and sky settings to achieve the results you need. I've opened the chapter 06 Hotel Lynda model and I've selected the chapter 06 proposal. Before we go any further, let's reset our application options, so we're all working with the same settings.
I'll click the Settings and Utilities icon and then Application Options, Restore Defaults, and then OK. As a final step, I'll click Regenerate to regenerate the model and apply the default settings that we've just chosen. Next, I'll pick the Hotel SE Iso bookmark, which will zoom us in to the hotel property that we've been developing. In this video, I want to talk about the sun and sky settings. To access those, we'll click the Presentation icon and then Sun & Sky.
I do want to check one more setting, though, before we continue. Let's go to the Settings and Utilities icon and click Visual Effects. Make sure that your Animation toggle is turned on. Turn that off and go back to Sun & Sky. Let's look at the Date and Time section first. InfraWorks contains a very accurate sun model, meaning that it understands what time of day it is, what day of the year it is, along with your geographic location.
It also looks at the three dimensional aspect of your model and all of the objects in it and how they interact with the sun and its current location in the sky. What that enables you to do is change the time of day and watch the color of the sunlight change and watch the angle and intensity of the shadows change as the time of day changes. This also works for the day of the year. If I were to set the date to the middle of summer, let's say July 25th or around that date, mid-July.
Let's look at about 4:00o'clock in the afternoon. If you look at the lengths of the shadows at that time of day. The sun's still pretty bright and the shadows aren't incredibly long. But, if I change the date now to, let's say December, we're nearing dusk during that same time of day. So, I'm just trying to show the accuracy of the model in that it doesn't just look at time of day, it also looks at the day of the year as well. Let's look at the next section, which deals with Wind & Clouds.
Before we do, I'm going to orbit the model away from me a little bit, so I can see the sky in the background. I'm going to talk about these from bottom to top, starting with Cloud Cover. As I move the slider for Cloud Cover, you can see the day go from rather sunny to quite overcast and dreary. I can also adjust the Wind Speed. You can see that those clouds are actually in motion. The more I crank up the Wind Speed, the more it looks like a stormy day, to the point where it's almost a little too fast.
I can also set the Wind Direction as an added level of realism, maybe to match the prevailing direction of the wind in the part of the world that I'm in. As you've seen, the Sun & Sky asset card provide some amazing tools to add realism to your model, as well as perform some practical and detailed analysis of sun and shadow angles. Now that you've completed this video, you can adjust the Sun & Sky settings in your models.
