Again, thank you for your fantastic plugins. They've revolutionised the way I produce my models.

I too am having the same issues. I'm running SketchUp 2017 with V-Ray for SketchUp 4.20.02 on a Mac.
When trying to render the animation only the 1st frame is repeatedly rendered.

When I process without VRay it works fine and also the preview in SketchUp displays fines.

Thanks you in advance.
