I'd definitely like to see some okay from the team before doing an update to the age.
I could give now a long answer which explains how cameras in Relativity must work and why they are limited in functionality, but judging from what happend when I gave a long answer, I prefer a short answer now:
Yes, the ability to look up and down has been turned off.
The slightly longer version of this is that the camera ought not to work at all in Relativity. I'm serious. Uru''s camera control goes totally nuts when the avatar does not face upwards anymore. There's only one kind of camera that can deal with this (I don't know the details here, it's somehow attached to the avatar, to it changes direction accordingly). This camera does not have a first-person mode, nor does it deal with colliders in the surroundings - it just rushes through all the walls. The fact that Relativity seems to have, in all four (!) "directions", first-person cameras and a camera avoiding collisions, is the result of some really great programming by tachzusammn. I mean, I wrote lots of weird Python stuff for Uru to extend the basic KI from Uru:CC with all the functionality that it has now - and still I am in total awe that he managed to get the camera working that well, not to even mention all the other scripting he did for this age. Thinking about how complex this must be - it's plainly mind-blowing.
/me raises his hat
(Sorry, tachzusamm, for explaining this for you - but I felt it should be said)
