Re: applied effects can make layer vanish - with no parameters altered...

Hi Niclas,
Thanks for the gracious response.
What I was trying to do is relatively simple.

I make a lot of videos which incorporate lousy still images which have to be animated. I do this over and over again and its usually a zoom in or zoom out from and to full size image. The only thing that will change is the point it zooms in/to from.

I was trying to make a few generic, sexed up, slightly 3D moves and include things like lighting effects etc. but i started with just the spotlight.

What I think is most confusing, is how the connection between FXFactory and QC breaks the plugin. If you open a plugin in FXFactory, then select it and choose to Edit it. This opens QC. Then do nothing at all to that plugin, and Save As... Then create a new plugin in FXFactory using that unchanged new QC composition, it will not work, it is broken! This, at least, for me, is a major stumbling block for anybody like myself who hoped to make a plugin without understanding why it gets broken taking this (should be no-brainer) route.

Thanks again,
Cheers,
Mark.
