Nested Precomps blurry with 3D Camera

Hi there,

I wonder if someone could help me with this, I can't quite figure out why it's happening.

As you can see in screenshot 1, I have a camera parented to a null. There is a text layer in the comp shown which is crisp and I have a nested precomp ('Static Equilibrium Box') which is blurry. You can see how it blurs in screenshot 2. When these layers are in the parent comp they are crisp but when precomposed and nested they become blurry. The same is true when rendered out. 

I'm using AE 2023.

Any thoughts on what I'm missing would be much appreciated,

Thanks

Frank
