With Havok 4, it seems you stay seated just fine, but I've been having terrible trouble with another effect in my sculpty vehicle; either the controls are being dropped, or the script is being frozen. It seems more like the latter as I've done repeated control calls just to see if it needed to be called again after the prim change.
If I turn off the prim change, the vehicle works just fine so it's directly tied into that PRIM_TYPE call.
Has anyone played around with this enough to see if: 1) It's really a sculpty bug 2) What's happening with it 3) Any neat work arounds 4) I'm just rockin' the ganj
I'll be fiddling and testing it so if I come up with anything new I'll post it here.
