Hello,
I'm getting a camera mismatch issue inside Houdini. We export USD and alembic cameras from Maya and we are having problems with both cache types.
When using an alembic camera (alembic archive node), I cant see the Arnold tab that allows tweaking of Arnold parameters, and with USD most of the time aperture value does not match with Maya original camera and we have to modify it by checking the values in Maya.
Are these known issues ? Are there any workarounds.
Appreciate your help.

When you Load the Alembic or USD in Maya does the wrong aperture mismatch show up?
In the USD File does the aperture looks correct? when the exported file is wrong it could be a maya export problem.
i don't use Arnold so i can't give a solid answer but it could be that the Arnold plugin doesn't recognize imported alembic cameras or the parameters are not exported in the alembic file.

I have sme problem here I think. When I import USD camera I have different view in Houdini compared to Maya. Just simple example what is right out of the camera FOV in Maya, it is still visible in Houdini with imported USD camera. I tried matching it with edit camera node but no luck.. it should match when FOV and aperture numbers are same but does not work here. Any ideas?
