0:05 We're going to kick off our bonus course with our finshed model just where we left it in the day time scene in the previous lesson.
0:14 But before getting started with the dusk view, we need to switch our render output settings back to test mode.
0:20 As a reminder, that means turning the interactive settings on...
0:27 making sure our quality is still turned down...leaving 'Denoiser' on...
0:33 Then switching the dimensions to a high of '2000 by 2000' square [pixels], to something smaller like we had before.
0:42 I was using 450 by 450 [pixels] so I'll use that again.
0:47 The only other setting we want to adjust is to make sure to turn our grass 'Fur' off in the 'Geometries' tab which will help speed up our test renders.
0:58 Now I can kick off a test render to make sure everything looks good...and it does so we're good to keep going from here.
1:10 Our gola for this bonus course, is to get more 'bang for our buck' and to be able to convert this model we have now into a dramatic dusk view...
1:20 while at the same time, keeping all of our daytime settings so we can switch back and forth.
1:27 Here's a preview of the finished dus
1:31 Don't worry if it looks intimidating at this point because it's really not.
1:36 We're going to be repeating most of the same steps as before.
1:40 But this time, a lot of the legwork is done for us from our previous effort.
1:45 So really we'll just be adding a few ne key details like artificial lights.
1:52 Let's just jump right into it.
1:54 By adding an additional Dome Light and HDRI.
1:60 I'll make a copy of the Dome Light we have in our model now.
2:04 And with the new copy still selected, I'm going to 'make it unique'.
2:10 The in the Asset Editor, under Lights...we can see that there are now two Dome Lights with the copy indicated by a '#1'.
2:22 I'm going to rename the copy now by addding '_Dusk' to it in order to make it easier to tell them apart.
2:34 Since we don't want two of the same HDRI files...let's browse to another file that I've included with your exercise files in the 'HDRI' folder.
2:49 Once loaded...reset the intensity back to the default of '1'.
2:55 Now let's test this sunset (dusk) HDRI but first, we're going to have to turn off daytime one.
3:06 Then we'll start up our Interactive Render...
3:15 ...and there it is. What a difference that one little change makes doesn't it?
3:23 And since we made a copy of our previous Dome Light versus adding a new one, the 'Use Transform' option is already checked.
3:34 So if we were to rotate the Dome Light...we can see some variation in the clouds and the direction of the light.
3:46 I think it actually looks pretty good with the pink clouds off to the right side, so I'm going to leave the arrow pretty much facing head on to the cabin.
3:57 So technically we could end the lesson here since this was all we really needed to do to switch from a daytime to a night-time view.
4:06 But I did want to show you a little tip for making it easier to switch back and forth between the two – should you want to render the day or dusk down the road.
4:16 This trick requires three new tags to be created.
4:23 Go ahead and name one of them '(V-)All'...then the next '(V-Day)'...
4:30 and finally...'(V-)Dusk'.
4:34 I like to add a 'V-' prefix to my tags indicating that these tags are specific to V-Ray...
4:41 and therefore they will all stay organized together at the bottom of my tags window.
4:47 So then we can go ahead and assign the 'Day' Dome Light to the 'Day' tag...
4:57 The 'Dusk' Dome Light to the 'Dusk' tag.
5:02 And remember that earlier, we added this Sphere Light here to the middle to brighten up the facade...
5:08 I think that light should show on both the day and dusk view so let's go ahead and move that light to the 'All' tag.
5:20 With our environmental and artificial lights assigned to tags, we can now set up some scenes to control their visibility.
5:29 Create a new scene base off of our current one.
5:35 And then name the one (scene) on the left 'Day'...
5:43 and the one on the right 'Dusk'.
5:48 And then turn the appropriate tags on or for each –
5:54 remembering to leave the 'All' tag on for both...and then update your scenes.
6:02 Don't forget to go back into the Asset Editor and make sure that both Dome Lights are turned on and showing.
6:09 Since we're now using scenes and tags to control visibility, we don't have to worry if both HDRIs are active at the same time.
6:20 Let's go ahead and do one more render to make sure everything is working correctly.
6:25 I'll start with the 'Day' scene.
6:29 I'll give it a second...
6:32 and then switch over to the 'Dusk'.
6:37 And there we have it. Not only was this method super fast for changing the environmental light...
