Hi, Per,
thank you very much for such a detailed description! I really didn't expected
it is something wrong with the file itself.
So, can I override these opacity parameters in osgviewer somehow or I need to
solve the file instead?
And, maybe you have some idea, why it can freeze the osgDB::rea

Hi Alexey,
To override the alpha value for the model you could write a node visitor
that collects all materials and changes all alpha components. I would
probably change the files and remove the Tr field or change it to 1. A
perhaps better solution would be to pass an option to the obj plugin
Hi Chris,
I've used a number of versions of visual assist, great bit of software, but
they all have this problem. I've just got into the habit of typing '.' then
backspace which puts things right and up the member functions. Since the
utility functions aren't used that often it's not too annoying.
Very nice,
we are defiantly going to enjoy OpenSceneGraph 3.0
Thank you,
René

Hi. I'm wondering if anyone had a recommendation for building the latest

seem old, an

You can use the osg::ShadeModel state attribute to enable flat shading.

Hi Jeremy,
you might take a look at ShaderGen utility from

while not being intergrated with osg - you may extract glsl shaders from

You will need to create an instance of the osg::ShadeModel class and apply
