Brown splodges on animation render

Hi there,

I’m doing a simple orbit animation in UE5, and when I render, I seem to get these brown marks on my model. In the standard viewport, and camera viewport, it’s fine, this only happens after rendering (images below).

Can someone explain what I’m doing wrong or suggest a way to fix it? Feel free to treat me like a complete idiot, I’m totally fresh to unreal, so explain things like I’m 5 please haha.

For context, the model has been imported from Alias>VRed>Unreal as an FBX. I’m also using the default Automotive Cinimatic turntable map, which I’ve bodged to this point.

Many thanks:)
