Hi,
Juanjgon,
I'm having troubles exporting orbx with static camera:
the camera field of view jitters when opening the orbx. I took a video showing what I mean.
Would you know what's causing the issue by any chance ?

Thanks!

Let me check it. This problem is usually related to a precision issue in the .orbx files internal floating data because the coordinates of your camera/scenes are too big (or small) to fit in the simple precision floating format used by the .orbx format, although in your case I'm not sure if this is the problem ...

Thanks,

I'm still investigating this issue. It is really weird, really I can't understand why it happens. It seems again some kind of precision issue, but at that scene scale it makes no sense. I hope to know more soon ...

A small update about this issue. I've found that the source of the problem is an inconsistency in the animated FOV data stored in the .orbx files, but I'm not sure why this happens yet. I hope to know more tomorrow ...

Ok. I've found the problem. It will be fixed in the next plugin builds. Finally, the bug was a tricky issue related to the cameras FOV motion blur and animation data format.

Thanks for reporting this issue!
