Broken: (works but not as should (IMHO)

Short description of error
error with camera rotation

Exact steps for others to reproduce the error
in connected (I hope) file first rotate camera around Y aix by 90 degree (to changew proportions)
after that when I rotate around X aix I got rotation arround Z with minus
Z aix rotation gives Z aix results
so when I have
X: 10
Y: 90
Z: 10

result is the same as
X: 0
Y: 90
Z: 0

And I have no possibility of rotating the camera in X aix

I think it should not (if Z aix transform is sitll same, then X rotation sgouldn't be rotated arround Y)

Pretty sure it is gimbal lock, Try changing the rotational axis to YZX or YXZ

Hey @Krzysztof (zgrzys),

I don't know if I understood correctly. Do you refer to the -0º and 0º that appear on the Transform tab?

Yes, this is how Euleur angles work, nothing wrong here (it’s not intuitive, but that’s math).
