ALT + LMB for orbit view not working

Hi guys, can you say me please why sometimes (and for different projects) alt button + lmb doesn’t work? In the project I’m working I can’t orbit the view! (Mmb not working too). I tried to restart my pc but the result is the same. Bug?
Any solution?
Thanks a lot!

Most likely you have your Scene Camera set to an Orthographic mode. Check out this intro page from the docs:

Hi, thanks for the answer but it doesn’t works! My main camera hasn’t the “ortographic mode” selected. When I press ALT I can see the “eye” icon but instead of orbit I obtain a simple pan.

The Main Camera and the Scene Camera are two different things. Watch the video I’m attaching and see if it clears anything up…

Thanks!!! This video answered my question :stuck_out_tongue: I clicked the yellow square, (i think it’s not normal) nothing happens…apparentely. But! The ALT key now work! :slight_smile:
Thanks a lot again!
