In this tutorial, we want to learn how to light in internal SketchUp projects with the Thea Render plugin.
First, we will produce a suitable background.
We can separate the background from the photo with the clipping tool in Thea Render Material.
Just copy the original texture in the clipping section and edit the photo so that the background is white and the buildings are black.
Pay attention to the distance, size and horizon line of the background to the camera.
One of the lighting methods in internal projects is the IBL method, which we mentioned earlier.
In the IBL method, we use HDR images.
But I prefer the default sky and sun method.
As you can see in the test rendering, if the default sky and sun are turned off, we won’t have ambient light anymore.
Only the background emits light.
Because in the background material, we activated the emitter property.
If the emitter also turns off, we will have no more light. ( from outside ).
So first we turn on the default sky and then we turn on the sun.
Don’t worry about default sky and sun power.
Because we will use the relight feature.
With relight, we can turn on, turn off, decrease and increase all the lights after rendering.
