You're doing everything right except one small thing, which I will be changing in future versions of osgWidget. The transparency is working, but the background widget of the Window you put your Widget in is probably full white. So: Window->getBackground()->setColor(0, 0, 0, 0); ...and you should be good. :) > imageSrc is a PNG transparent file, but I can't see the trasparence. > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=39637#39637 > > > > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
