Camera-less viewport frames

Has anyone used viewports without a camera instance? I was testing some things and found out that models still render inside a camera-less viewport as long as they are positioned relative to a 0,0,0 world position and I based part of my item frames ui on it

I have yet to find any mention of this behavior on the devforum or anywhere else.

Reason I’m asking is that I’m running into a lot of unexpected behavior, for example: manually copying a model from one viewport into another viewport results into the second viewport displaying the model differently (it basically gets flipped upside down) (even

I know this is a hacky way to do this but was wondering if anyone tried it before and if I’m just doing something wrong or if it’s just not meant to work like this at all.

If anyone is aware of any previous discussions or resources related to this I would also greatly appreciate if you shared them, thank you!

I’ve never been able to display anything in the ViewportFrame without a Camera and as far as I can tell that’s the only behavior I can replicate in my Studio. Did this behavior continue after you reopened the project?

Yes, to replicate, create an empty viewport, place a part inside it, set the part’s origin to 0,0,0 and and then move it around on the Z axis, setting it to -10 should make it render.

This is something I am using in a large project but as far as I am aware, it’s undocumented viewport behavior and is definitely a hacky way to do it.

You’re right that time I got it to work with a new ViewportFrame. It didn’t work the first time though, but I actually deleted the original ViewportFrame and when I undid that action the Camera was gone and the Part was still visible in the ViewportFrame.
