Map doesn't fully show/load

I’m new to Blender and began yesterday. Today I created my own little Town, and wanted to render it with Cycles. But the full map doesn’t load. It only shows half of it and the rest is grey. Same problem with Eevee. Can anyone help me? I also uploaded an image. Screenshot 2021-04-28 135949|690x397


It has to do with the clipping value. It used to be in the N panel under the view tab, can’t remember with the new version. I’m at work so can’t check either.
