I've been having this problem, and I don't know why. ill just give some context. I had imported this model from SketchUp, along with the camera view from there. It was working fine, until I decided to delete the SketchUp cam, and decided to add a new one. I've been having problems since I added the new cam. The model is just fine, and so are the materials, When I put the viewport shading into any mode the model looks fine, however when I decide to render all I get is a grey screen when it finishes rendering. I'm using the cycles render engine. I have read all of the other forums that are similar to mine. I have checked that its not an issue of clipping, or depth of field, or that it is a material problem. I just seem to be stuck. Would be great if someone can shed some light on what I'm doing wrong
Many thanks in advance
