How to stroke text using C4D renderer

Hi all,

I'm working on an architectural project in after effects where I've got shapes that extrude in 3D to highlight various rooms using the geometry options on the shape layer (which is only available when Cinema 4D renderer is used in the composition settings),

The issue I've found is that when using this renderer, I can't use basic effects such as text stroke (or the fill effect - though I don't need this right now, just highlighting it doesn't work on text).

How do you apply a stroke/outline to text when using the C4D renderer?

Alternatively if the above isn't possible, how do I extrude shapes not using the C4D renderer?

Many thanks in advance.
