VRay for SketchUp Manual
Add LightsWe haven't added any light to the
scene so far. However, the render still looks good. The shadow is kind of smooth
because we used GI as the only light source. So we still need to add more lights
in order to have more depth to the image.
1. From the V-Ray toolbar, select the
seventh icon from the left (Create Rectangular Light).
2. From Top view, follow the steps below
to create Rectangular Light in the scene.
3. Start from bottom left.
4. To complete creating the light, make
your second left click to the top right of the scene as shown.
5. Select this Rectangular light you just
created.
6. Go to the Front view, select the move
tool and drag the light to the top, approximately 4X of the height of the chair.
7. Render it and you will get a very
bright image like the one below. That's because the V-Ray's default setting of
the Rectangular Light is set to No Decay. Please follow the steps below to
adjust it.
8. Select the Rectangular Light. Right
click on Object, select V-Ray for SketchUp and click Edit Light.
9. Uncheck the No Decay. This will make
the distance between the light and objects being considered while rendering.
That means the object further away from the light will get less light and become
darker. To make the object brighter, you can either increase the intensity of
the light or move the light closer to the object.
10. When uncheck the No Decay, the
default setting of the intensity is set to 30. Please change the Multiplier from
30 to 4.
11. Hit Render again and you will get a
much better result like this one below.
Here are some images with different intensities.
