Surface animation and bone motion

[Dave]

Hi - a couple of questions. Is there any way within Vizard to simulate waves on a surface - controlling the height and direction with external variables. I have looked at some things - e.g. dlr files but would like to be able to directly control the surface if this is possible.

Also - if animating an avatar with bone.seteuler is there any way of making the action happen over a period of time instead of instantly other than looping a lot of smaller movements?

Finally - in version 3 -when I add the biohead it seems not to replace the existing head - you just end up with 2 heads. Removing (renaming) the head mesh file solves this but I just wondered if this was intended?
