The HD render has some very obvious clipping problems, but it took a long time to render. So it will have to do. Will try and see if there are any settings I can make different for the next scene.

I think I will do as Lee crystal said and try making the engineer scene next. I have actually forgotten to make the engineering bay that is supposed to show in the background...

I might set up a task for .blend objects that fit in an engineering bay...
