A quick comparison with our previous render using the Render History window will
show that we have shadow edges that, while still retaining a measure of softness,
now appear decidedly sharper than they were.
This then is a very nice approach to creating exterior daylight that can give us a lot
of flexibility regarding the way that both light and shadows work in the scene.
Creating even stronger occlusion shadows
As one final touch, just in case we feel that the occlusion shadows we are generating
through the Dome light are still not quite as strong as we would like them to be, we
can very easily go ahead and enable the Ambient Occlusion option that is a part of
the GI controls.
To do that, perform the following steps:
1. In the V-Ray option editor, click to open the Indirect illumination rollout.
2. In the Ambient Occlusion section, put a check in the On box.
3. Set the Radius value to 15 .
4. Set Amount to 0.5 .
Of course the difference that these changes will make to the image will be subtle, but
in reality, that is exactly what we want them to be—slight tweaks that help ground the
render just that little bit more in reality.
Creating a better sky
Another tweak that we may want to perform in render as it were would be to create a
better-looking sky backdrop than is currently on view. You may have noticed in your
renders from the Looking at the Sky scene view, that our sky currently looks ex-
tremely soft and nondescript. This is not surprising as the lighting specific HDRI that
