im trying to make a simple skydome and it shows up in the viewport but when i render it out its all grey. another thread said the image had to be assigned to a material and not just uv mapped to the sphere but i cant find any way to add a material to it. here is the blend file if anyone is able to help https://www.dropbox.com/s/ltxh99z8ex52u8k/grass.blend
Have you changed you cameras “clipping” distance. You may have change the clipping distance for your viewport, but you also have to set it for your camera.
