Hi Li, I have just added the StateSetManipulator to the osgshapde example to see if back face culling is the reason, what I found is that the windings on the triangles are the reverse of what they should be. Is this probably down to a recent change to avoid using GL_QUADS for GLES/GL3 builds. I'll have a look at fixing this.
This winding issue "might" be what is causing the problems you are seeing, it would be worth disabling back facing culling in your app to see if that changes things. Robert.
