I have two virtual cameras with the same position but different lookAt targets. When they look into more or less opposite directions and then I blend from one into another, not only the rotation gets blended, but also the position. It goes by a full circle which is not desirable behaviour.
I set up the blend hint to cylindrical position which removed the Y position change, but X and Z still remain. How can I prevent the camera position to get blended?

It’s because they are using cylindrical blending while looking at different targets. The cylindrical algorithm interpolates the target position and camera distance from target, which will result in the circular path you describe. Change the blend hints to “None” or perhaps to “Screen Space Aim when Targets Differ”.
That’s odd…the initial hint was None, but I also already tried “Screen Space Aim when Targets Differ”. But the thing is now that it works…
Thank you 
Both cameras can have hints. If one of them requests Cylindrical but not the other, Cylindrical wins.
