Is the default Freecam working for you? Recently?

I noticed today that freecam (shift-P) isn’t working in a couple of my games. Was that feature removed by a recent update?

I can confirm this is happening for me as well while playing my own experiences with the RobloxPlayer, odd choice if intended since it was a very useful dev-only tool.

But I can help with this code taken right from that feature (LocalScript), simply give it to yourself with another script from Server only services to your Player.

Thanks, for now I’ll assume this was a mistake and wait for the next release to fix it.

It also happens to me, it works in Roblox Studio

I would post a bug report if it doesn’t seem to be fixed in the next update, Shame that it’s broken in the meantime.

I would post one too, if I had Regular status(after 3 years)! I emailed the bug support team. mega oof!

having this same issue too, hopefully it gets fixed soon!

It works in Studio. Another thing I’ve noticed that worked before but that doesn’t work anymore would be the wireframe view, which is quite odd. Did this update add something that corrupted a ton of stuff, or are these just typical Roblox decisions?

im hoping its just a bug, i cant see them removing freecam.

Roblox bug report Dev Relations sent me a reply about this issue, it was not intentional:

"Following up!

I talked with some engineers and the issue is not an intentional behavior!
Therefore, we are currently working on a fix, and will update you as soon as we have news!

Thanks for the report!"

Seems like this is fixed now. Working for me. yay
