Hi all, I have and osg::Box that is drawn using a osg::ShapeDrawable and I want to make it transparent. I have tried using the setColor method of the osg::ShapeDrawable as I understand that the fourth value of the vector passed to it is used to set the alpha value, but it looks like I need to enable the transparency somewhere else has it is just use the RGB components of the passed vector and draw a solid Box. Where can I enable the transparency for the box? Or what I need to do?
Thanks, Nicolas.
