Thanks for your replies.
In PFMP_APPCULLDRAW mode, the objects seem to move around
without a problem. However, the following line is output
over and over again.
38263 PF Debug/Internal: pfUpdatable::pf_addUpdate not called from APP
process=(null),Updatable=pfDCS
With APP_CULL_DRAW, there is definitely also a channels
problem, where a static copy of the object hangs around
for a while - while the moving copy carries on along its
path.
In one scene, we have a ship on a path which is behaving
itself today, but has misbehaved in the past. However,
in a model of a town centre, we have a van which is
consistantly misbehaving. All models were built with
Multigen, and are NOT animated within Multigen.
Is there some Performer thing I'm supposed to do to
propogate the new DCS across all processes ?
The more I learn, the more I realise how little I know.
Thanks, and have a good weekend.
Gary.
