Vray Section Rendering

[Chexmix26]

Hey everyone,

I was looking endlessly for a way to render a section with VRAY in Sketchup using a section plane. I had no luck and was struggling. I went over numerous outdated tutorials. I came across this youtube video which pretty much solved it all for me.

I thought i'd share so people wouldn't go through the same crap I did.

This only works fine if you only use raw geometry. To really cut through everything, after you apply the sectioncutface plugin, also use Zorro 2 which is also built in to the context menu of the section plane to remove everything behind the section plane.

Use it on a copy of your model though as it really deletes everything!

Here is SectionCutFace though: http://forums.sketchucation.com/viewtopic.php?t=20564
and here is Zorro 2: http://forums.sketchucation.com/viewtopic.php?t=16038

Here are some examples (both in perspective and in orthogonal views, rendered with Twilight):

Hi there everyone. !

Is there any way to control the light with these (or any other) tools, when rendering a section?
As the SectionCutFace actually cuts the geometry, the interior light is unrealistic, coming from the whole missing geometry, and not just from the windows.

Thanks a lot

do a plane with a double sided material on it, the side facing the interior could be the same material as the inner walls, the side facing the camera should be set to be fully transparent without refraction.. this cap should prevent the sunlight to pass trough the "section hole" but it is actually invisible to camera.. so you can render it seeing trought and keep realistic shadows avoiding the "dolly house shadows" effect.

below is attached a render i did a couple of year ago.. that was done in 3dsmax vray but i pretty much used a similar trick.. notice that not only you have proper shadow coming only from the window and not from the "roof hole" but you can also clearly see the ceyling itself reflected in the wine decanter..

hope this can be helpful.
