Does Clipping Work in Blender 2.9? From the Blender docs, it appears that when I create a view &gt; render regions &gt; clipping region (CMD + B), only the selection within the clipping should be visible, however:

I have tried different views. Also checked to see if, for example, Transform, would only with within the &quot;clip&quot;, and that doesn't happen either. Rendering also isn't limited to what's inside the clipping area.
So am expecting I am missing a step or otherwise misunderstanding either:

what is supposed to happen
how it's supposed to work
how to achieve it

Thanks.
From  your screen shot, you enabled &quot;render region&quot; rather than clipping region. Not sure what's the correct key bind in Mac OS, but in windows, it's Ctrl + B (Which might be eq to Cmd + B in common translation).
Please look at the menu again, it said Alt + B to create clipping region, as the following picture show. Red dashed line is for render region, and it's separated from clipping region.

Remember, It is &quot;clipped&quot;, not hidden. It should only be working in Solid or Wired Frame view mode. On the other hand, render region only works during rendering in Cycles.
