V-Ray and Rhino Retraced render full model, not the active vaSection

Hi all!

I’m having trouble getting a rendered image of a VisualARQ section. I am using a vaSection line to cut my model in the 3D viewport (Perspective), and it displays perfectly.

However, when I try to render this view, both V-Ray and Rhino Raytraced ignore the active VisualARQ section and render the entire, uncut model.

As a point of comparison, a standard Rhino Clipping Plane works perfectly and renders as expected with V-Ray. The problem seems to be specifically with the vaSection object not being recognized by the render engines.

I assumed this integration was fixed in earlier VA versions, so I’m wondering if I’m missing a setting. How can I get V-Ray to render the 3D section that I see in my viewport?

My setup:

  • VisualARQ: 3.7

  • Rhino: 8.25

  • V-Ray: 7.10

Hi @Elshareef Vray should render properly models sectioned with VisualARQ section.
I’ve just tested it with Vray 7.2 and Rhino 8SR24:

How are you pushing the render? make sure you do it from the Rhino Render command:

PD: The Raytraced mode is not compatible with VisualARQ Sections. We’ll need to fix it.

Hi Francesc,

I was originally using the V-Ray toolbar commands to render, which, as I mentioned, it didn’t work with the VisualARQ sections.

I tried your suggestion and used the standard ‘Rhino Render’ command, and I’m seeing some strange behavior:

  • The first time I ran the command, it worked perfectly! The section was applied correctly in the V-Ray Frame Buffer.

  • However, when I tried to run the ‘Rhino Render’ command a second time, the V-Ray window opened, but the entire model was gone (it just rendered an empty scene).

As a separate point, I also can’t get V-Ray Interactive to work with the sections, either through the V-Ray toolbar or the Rhino Render preview command.

Do you have any idea why the standard ‘Rhino Render’ command would work only once and then fail on the next attempt and why not through the default Vray toolbar as well?

Thanks,

Elshareef

Hi @Elshareef you are right, it looks like the Interactive render or the VRay window spoils the view with VisualARQ sections and it is not rendering the model sectioned anymore.
We will investigate if we can fix this from our side.
