I'll bear that in mind in the future. I dropped the ambient right down,
brightened and moved the lights and the scene looks much better

Is there any reason you use default to set the ambient, rather than

Yeah, the plane's just there for now. The iso is SLOW. A wall won't be
necessary
once all the vegetation's in as it'll be too thick (using images created in
Vue d'Espirit on
