Rhino 8 SR20 RC1 broke edge softening in V-Ray

I let my Rhino to upgrade to the latest Release Candidate - version 8.20.25133.14001
I then tried rendering a scene with V-Ray (version 7.10.00) and all objects that had edge softening applied have completely disappeared from the render.

Here’s Rendered viewport:

Raytraced viewport (Cycles):

And here V-Ray render:

All the other render-mesh effects like Displacement, Thickening etc. are probably affected too.

I have since downgraded back to latest stable version (8.19.25132.01001) where everything works:

I’m not sure whether this is a bug caused by Rhino or V-Ray but clearly something has changed in Rhino itself that causes this bug to manifest. I’d be great if this got resolved one way or another before SR20 is pushed into stable branch.
