Viewport issues

Hi,

I somehow managed to restitrict the view in viewport

This doesn’t affect rendering, but it’s very annoying when composing the scene.
How can I restore the viewport?

try alt+b (clipping border)

Thanks! I already tried ctrl+alt+b to remove render border (which it did), but this was new to me.

Looks like it could be a camera or a clipping setting. Could you upload the Blend and I’ll take a look?

Issue is already solved.

What was it?

I have absolutely no idea, but it occurred when I created a render clip (ctrl+b) on the viewport.
