I have been testing with trunk and have only come across one problem so far (this might not be a new issue).
I have a simple viewer set up with two nodes. The first is loaded from an osgb. Internally it sets the glBlendFunci(0, GL_MAX) via osg::BlendFunci.
The second node also sets glBlendFunci(0, GL_MAX). This is a geode with a geometry node under it. I am setting the blend attributes on the geometry state set.
At runtime the attribute on node two is set correctly but then immediately changed again by State::ApplyGlobalDefaultAttribute to GL_FUNC_ADD. The blend equation is also stepped on in a similar way. I am using apitrace to see the GL calls.
GL_FUNC_ADD is not part of either node that I can see. However, this problem does not occur with, for example, axes.osgt used as node one.
I could use some advice on tracking down where this default value is coming from, and why it is overriding a specific node attribute like this.
