I’m currently working on a perspective section.
For the perspective I’m working in Sketchup in our 3D model of the building.
I placed a section where I wanted it and added a scene for it, looking straight on. Now here is my problem.
I want the section cut to have visible light and shadow from the sun coming in. But the shadows are not realistic as the sun also is coming in throught the section opening, as if there weren’t walls behind it. It acts as if the section is a big opening.
Is there a way to have to sun only come through the windows?
For example, all those unfurnished rooms should at this point still be completely dark, since they have no windows yet and no other openings.
The only way to do that that comes to my mind right now is by creating two different scenes, one with the shadows activated and other without them, then create a masks on layout or use other image manipulation software.
Right underneath the horizontal section plane cover the building with a transparent png material that lets you look inside the rooms but that blocks sunlight coming in.
I never learned how to use SketchUp correctly it’s just all trial and error and lots of tutorials for me. I also only use it a few times during a semester to make a base vor visualisations or in this case for the first time a section cut.
