Hi, I use osgEarth::ImageOverlay::setAlpha(float alpha) to change the transparency of images, which was draped on terrain, just like what google earth does, but this method seems has no effect at all! It also doesn't work in the sample osgearth_imageoverlay. Is it a bug? I use openscenegraph 3.0.0 and osgearth 2.1.1, build with visual studio 2010.
Thank you!
