Backface Culling in Substance Painter Renderer

[Zer0Sum]

Is this not possible, or am I just missing a setting?

I have a model surrounded by a 3D background. This works fine in the main painting/editing window, but when I switch to the rendering view, I can only see the outside of the model, there is no backface culling.

This makes it useless for rendering.

The only option I have is break the background in half, export both halves, and then turn on and off each half depending on which side I am rendering the model from.

Is this the only way of doing this, or am I missing something?

This is the scene from within the main window:

And the same scene from the render window:

I am using Substance Painter version 2019.3.3.

Thanks for any advice!
