I have two spotlights within the niche well below the top edge. The light they project should be contained within the walls (surface objects) but when I set the view to [Rendered] the light appears to go through the walls as though they were translucent. Thoughts? Fixes? Note: if I actually ren…

Hello - can you please run SystemInfo in Rhino and post the results here? -Pascal

Here it is: Rhino 6 SR13 2019-2-27 (Rhino 6, 6.13.19058.371, Git hash:master @ 17cd8b51accbe17dd04b48028f49d5e77a67f17b) License type: Commercial, build 2019-02-27 License details: Stand-Alone Windows 10.0 SR0.0 or greater (Physical RAM: 16Gb) Machine name: RANDY_LAPTOP Hybrid graphics system. …

The lighting (shadowing rather) will fail for cases like this. If you turn on thickness for your wall planes and make them thick enough you will get better shadows. [image] The left instance has the wall extrusion without thickness, the right instance with thickness on and set to 0.4

Thanks! If I may, what you’ve done is change from a surface (no thickness) to a solid with a thickness of .4. Is that correct? There’s no way to set a “thickness” for a surface, right? (If that’s a stupid question, I humbly accept the label.)

Select your surface, then in object properties panel find the thickness icon, click it. Check the box and set a thickness that gives you the desired outcome [image]

Okay - I found the thickness option–never needed to use it before. But check this out: I set the thickness to “1” (inch) [image]

So I tried to “fill” the wall with a solid, but no change: [image]

Hi - according to the developer, this is to be expected as things currently are. Note that you could use the Raytraced display mode to get it right: [image]

You can try to install the Rhino Render Next as well: run _TestPackageManager and scroll down and install and restart rhino and choose it as the render engine for static renderings.

The Rhino Render also gives OK results, but the OpenGL displaymode is struggeling. Do note that Rhino Render and Raytraced display mode (or the Rhino Render Next) does give different results since the Cycles engine behind Raytraced is calculating bounced lights and adding this to the objects so the…

I don't think spotlights should do this. Am I wrong?
