Blender rendering is grey and black hello . how to get rid of this grey plane that hides my interior. in 3d view it doesnt appear but when i rendered it shows. I try to make some changes in render then camera setup.  please can anybody tell what to do.
It sounds like your object is hidden in the viewport, but not in the render. Press &#9095; AltH in the viewport to unhide all hidden objects, or examine the outliner for objects with their eye icon disabled:



The eye icon controls object visibility in the viewport and preview render, and the camera icon controls object visibility in the final render.
