I don't have access to the configuration I was using last week, so I
tried to reproduce the problem on a different computer (running the same
OS) but to no avail. I tried the Debug, Release, and even the
configurtion in between (where you don't specify either, and get no
debug symbols and no optimization), and in every case, it works fine.
Last week I was using packages I got from arakhne.org, and in what I did
today I compiled from source. I did not try to use the packages today at
all. Since it's the last variable, I'm going to blame the packages at
this point. Maybe I'll get some time to try them tomorrow to make sure.
Thanks for your help,
Alan.

Robert,
To reproduce the problem, I simply ran the osgsequence example from
OSG 2.6.0 in Linux. The sequence example just sticks at the first
frame on both sequences. The 2.4.0 version of this example executes
the sequences as would be expected.
I'll try the 2.6.1 version today and let you know.

Hi Alan,
osgsequence is working for me. Could you explain your exact steps in
recreating the problem in osgsequence so that others can reproduce the
problem. If we can get others to reproduce the problem then
hopefully we'll be able to see a pattern emerge that can help use home
in on what the problem is.
W.r.t state needing to be dirtied, this isn't relevant to
osg::Sequence as it doesn't have an state, it's just a self contain
node, that only affects traversal of the scene graph, not any OpenGL
state.
Robert.

Hello,
First, I'd like to say Thank You to Robert, Simba, and Chris Denham for
helping me with my last problem with the DatabasePager. Chris's suggestion
worked great.
I just recently upgraded from OSG 2.4 to 2.6 because I needed multisample
support for my FrameBuffer Objects. When I did this, everything worked fine
execpt for two things which may be related. The first was with osgEphemeris,
and I found someone in an archive who was able to fix that problem by making
sure that the computed sky texture was marked dirty() when changed. Robert
said on the list that it "[had] been relying upon an inefficiency in the
osg::Texture2D::setImage() method that has now been fixed, so only really
worked previously by fluke." This leads me to believe that maybe more
efficiency changes were made between OSG 2.4 and 2.6 which could be causing
my next problem.
The second problem I have is that none of my Sequences seem to work right. I
tried a lot of things outside OSG to make it work, and eventually did a diff
on the OSG 2.4 version of osg/Sequence.cpp and the OSG 2.6 version to find
out that they are identical.
The problem goes like this. When I load a model with an Sequence in it, the
sequence runs one time. I cannot restart it ever. If I load the model, then
find the sequence node and stop it before it's drawn, I can never start the
sequence. This worked great in OSG 2.4.
So I built the osgsequence example in 2.4 and 2.6, and as I suspected, the
2.4 version of osgsequence works great, but the 2.6 version does not.
I'm not sure what the problem is, since like I said, Sequence.cpp hasn't
changed at all. My suspicion is that, like the osgEphemeris problem
described above, something in 2.6 has been fixed so that it requires
notification of a change of state in the Sequence (something like a dirty()
being called?). Of course this is only suspicion, and I have not been able
to debug it very well. I'm hoping someone who knows the code better than I
do will be able to find the problem quickly.
So I guess that's it. I think that if the osgsequence example could be made
to work, that my sequence problems would be fixed.
Thanks for all your help, and again, thank you for Open Scene Graph,
Alan.
