Hi everyone. I've been trying to render a floor plan in top view but showing sunlights coming through the windows and not the ceiling. Because I have to see the entire top, I have to either leave it open, or use a section cut; but either one allow sunlight to enter from the top.

Easy >Camera>Parallel projection If the floor is overexposed, chances are that you've made one of those surfaces emit light. Don't do that...

Is there a way to make the ceiling cast shadow but invisible to see like in 3ds Max?

The best way to deal with those IMO is to turn shadows off and render with a pale gray uniform background. Makes a clean plan render. If you really want to show some light coming through the windows maybe you can try placing LEM in the windows..

This got me thinking in photography terms again. What's needed here is what photographers call a "flag." Jargon for other similar devices include "gobo" and "cuculoris" (or "cookie") , but this is just a simple flag. Here's an example: two vertical faces shade the overall plan while letting sun come through the windows. With results like this: Some work was done in Photoshop to remove the flagging surfaces from the final image.

I have a technique to deal with this issue, though I see it from a slightly different take as an interior designer. I want to create shadows under furniture pieces and other items in the model to give it some depth, but don't want the walls to create shadows either. You can see my attached image for the look that I'm going for. I use Podium's material properties box to deal with this issue by unchecking "cast shadows" in the appropriate materials on the walls. (see attachment) Usually the list is fairly minimal: wall colors, color for top of walls, and the materials used for the windows and doors. It takes a little back and forth with rendering since you don't see the effect of this until you've rendered. If I'm doing a floorplan in SketchUp and not rendering it, I can more easily accomplish this by making a quick group of everything above furniture level, putting this on a layer called "no shadow" and then have this layer not cast a shadow by using the entity info dialogue box. (See attachment 2) It would be excellent if Podium could be made to recognize this "no shadow" option in the entity info box so I could use the same method for both rendered and non-rendered images. Hope that helps!
