Ahhhh thank you so much!! That worked a treat (you can remove profiles & edges in the Styles settings). Super easy instructions to follow, thanks man! And yes, was already using scenes (just makes it easier to re-render something if you got half way through editing in PS & then realised that you had to tweak the model!)
Thanks everyone for all your help! Sorry for being a Sketchup retard - I’m not new to Sketchup, but am new to the idea of rendering direct from SU, so I’m clueless about all the settings involved! (I used to always export to 3DS Max, but don’t have my licence anymore)
