Problem with double sliding door glass render

Does anyone have any idea why my double sliding door glass would be a light blue color vs my surrounding curtain wall that is rendering gray. Renderer is vray for Rhino.

Thanks, James

Maybe check you layers. The glass in the door could be set on a different layer with a different assigned material than the glass in the curtain wall.

@avatarlucas Can you share that file? that way we can better figure out what’s happening.
Thanks!

Hi @fsalla

Find another screenshot of the problem from a different angle in Vray as well as the file attached - I had to take all the textures out to make the 20MB file limit but the glass is still the same problem.

Thank you

Hi Thomas, the glass is on the usual VArq layers… so the doors are on Door layer and the Curtain Wall on Curtain Wall layer.

Thank you

@avatarlucas I see what happens.

On one hand, the glass component of the door has a thickness, so it’s actually a polysurface. The glass component of that curtain wall (the “cell”) has no thickness, so all panels are actually surfaces. If you give a thickness to the curtain wall cell, both door glass and curtain wall cell will render with the same appearance.

On the other hand, VRay is rendering the glass material on surfaces differently on each side of the surface. So the render result will be different depending on the direction of the surface. If you set a “0” thickness to the door glass and the curtain wall cell, you may see different results depending on the direction of the surfaces of each object. You will appreciate this better if you explode these objects and flip the direction of one of the surfaces of the former curtain wall cell panel. That’s something we can’t help, since it’s VRay how it deals with this material and the Rhino surfaces.

But this seems to happen with the Rhino Glass material. If you use a VRay glass material, you might not have this problem.
