However, you may be asking: aren't the default settings good enough? Well, you
probably will be able to answer that question after this reading and applying the
techniques covered. Let's add the
Shadow
effect that can be found under the
World
tab. However, before we move further, there is something we need to understand.
Working of shadows in Lumion
In order to correctly tweak the shadows and spot any issues, we need to understand
how Lumion works with shadows. Once again keep in mind that Lumion is a real-
time application and to prevent flickering or any other shadow artifacts, Lumion
applies the shadow on top of every surface with a small offset. It may happen that
we are creating a close-up of some 3D models to look as if they were floating with no
contact with a surface. This is when we need to correct or tweak the shadow.
Correcting shadows
As explained in the previous topic, in some situations, when the camera is close to a
3D model, the shadow has an offset in relation to the 3D model giving the impression
that we have a serious case of floating objects, as shown in the following screenshot:
The image on the left clearly shows the offset between the 3D model and the shadow,
but the image on the right side is correct because we used the
Shadow correction
setting as highlighted in the screenshot. This is the first step to start correcting some
issues with the shadows, but if you look closely at the previous screenshot, there is
another aspect that needs to be taken into consideration.
