Thanks for the help guys, I think Guy may have hit it on the head...
After much fiddling, I've discovered that everything is in fact working as it should, however more often than not, the UserDataBlob is not being seen to have changed...
Following my ranting a few weeks ago about how we have no way to emit particles based on change of velocity I decided to make a acceleration weightmap SCOP. I use the UserDataBlob to store the point positions from the previous two frames and this needs to be updated every time the current frame changes... Unless I open the UserDataBlob's PPG and toggle a parameter, it's output port doesn't get updated. If I toggle it from within the SCOP (
i.e. add some toggling code to the SCOP) it seems to have no effect, and anyway seems a totally ridiculous thing to be doing!
AlwaysEvaluate seems to have no discernible effect either....
How can I make my UserDataBlob feel more wanted?
Thanks for the tips,
DAN

Make sure your UserDataBlob is actualy 'needed' by XSI, else your
operator will not be triggered for updating the UserDataBlob.
How is used your UserDataBlob ?
