In the future, please post more details (what exactly is wrong / where exactly is it / is it a regression) - you can't expect us to know every detail about AF.

The problem is that arx has a very crude frustrum clipping code (ARX_SCENE_PORTAL_Basic_ClipIO) that only checks the frustrum against the objects position and an arbitrary fixed radius. Now the stalactite object doesn't actually fall - it just activates an animation that moves it further down. This doesn't change the object "position", just the offset of the vertices from that position, so the object still gets culled when the original position gets out of view. The same happens with other larger objects such as the dragon - it gets culled before it's fully out of view.

So this is how it works. It is just annoyance, mostly, but this stalactite "disappears" right under your feet, which is quite frustrating.

Yeah, it's something that will be fixed at some point - not sure when though.

I'm curious though: what do you need to stand on the stalactite for? It doesn't really help you access to anything new, right?

Are you joking? The player is clearly supposed by developers to stand on this stalactite! There is fully voiced in-game hint!

Hm, right, it's been a while since I played that part.
