0:05 We’re now finished creating our scene and from this point on, we’re just going to look at little tips that will improve the render qualit...
0:15 and reduce the need for additional post-production [editing] in programs such as Photoshop.
0:21 Let’s start by turning on a subtle, but important setting called ‘Ambient Occlusion’.
0:27 Ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting.
0:39 In the ‘Asset Editor’, under ‘Global Illumination’, there’s an advanced properties dropdown...
0:48 with a button for toggling ambient occlusion on and off.
0:54 To see its effect, I’ll start with my materials override on…and create a render region focusing on the where the wood siding meets the shell frame.
1:09 After toggling 'Ambient Occlusion' on, you should notice a subtle darkening at enclosed and sheltered areas, like the corner joints and recesses between slats.
1:21 This detail affects the rendered image's overall tone.
1:25 Here it is on…and then off.
1:34 And then finally, I’ll it leave on.
1:40 The next tip is to look at some physical camera effects that will help add some drama to out scene without the need to go into Photoshop later.
1:52 Under the ‘Camera’ settings is an option for ‘Effects'.
1:56 Open that up and find ‘Vignetting.’
1:60 Enter a value of ‘1’ and notice the subtle darkening around the edges of the frame.
2:06 Like ‘Ambient Occlusion’, these subtle effects add up and help to differentiate the quality of your renders from others.
2:17 Next, let’s make some exposure and color corrections right here in V-Ray.
2:22 In the ‘Frame Buffer’, there is a little icon in the bottom left corner that opens a side panel with a bunch of editing options.
2:32 Next to the corrections icon is another helpful tool called ‘Force Color Clamping’ – which shows the areas of the view that may be overexposed or blown out by our camera or light settings.
2:46 This will help guide the corrections that we’ll want to make to balance the brightness and exposure.
2:54 Next, enable ‘Exposure’…then bring the ‘Highlight Burn’ down until the over exposed areas are more balanced.
3:04 I don’t mind a little blown out areas since the sun is pretty low in the sky and intense this time of day.
3:13 Next we can adjust the exposure up a little to compensate for the highlight burn reduction.
3:21 And then even boost the contrast a little bit to show even more definition of the materials and color.
3:31 And with those [corrections] it's actually looking pretty good.
3:34 Next, under the 'Exposure' settings is 'White Balance'.
3:38 I think the fall colors and HDRI is starting to cast a bit too much warmth so I’m going to adjust the temperature a bit to the left to compensate for that.
3:51 Alright, I think it’s there and I hope you all at home agree that our effects are really adding up to a nice final result.
4:02 Keep in mind that this part of the process is all about personal preference and I know that these tips may not apply to every project or scene that you end up working on down the road.
