Hi Robert, Thank you for the tip, you are right.
I used osgConv without optimisation on my original openflight model, and texture are OK in both windows (for ive and osg). If I don't want the optimizer to unref images, I have to remove OPTIMIZE_TEXTURE_SETTINGS parameter, but what might I loss in terms of performance without this parameter enabled ? 2008/9/5 Robert Osfield <[EMAIL PROTECTED]> > HI Amalric, > > If you open the second graphics window after the first second graphics > has been rendered and they share the same view, and the texture's are > set up to unref images after apply, then only the second graphics > window there will be no image to apply.
