[osg-users] Alpha Transparency control

[Robert Balfour]

I want to put a stateset on top of a model subgraph to override the
alpha values of all its vertices, in order to have global control of the
model transparency. What's the appropriate way to set this up using
BlendFunc, BlendEquation, etc.?  Or is the only way to traverse the
subgraph and change all the alpha values of each vertex individually?

Thanks.


Bob.
