I'm trying the FBX plugin but I'm experiencing a couple of problems:
1) the model is not correctly oriented (no matter if I export using Y-UP or
Z-UP options within 3dsmax)
2) aniamtions don't start (I also tried to export using the 'bake animation'
option)

Another thing I also noted is related to transparency: I reduced the opacity
value inside 3dsmax material editor, but the model is always 100% opaque.
Is transparency currently supported?

You'll need to set the bounding volume of the osg::Geometry to

Hi,
quite not sure what happens to gl objects when switching QT widget to
fullscreen, I found a solution.
A node visitor calling releaseGLObjects() on drawables does the trick.

Yes, that is the meaning. However, the top of the hierarchy can use OVERRIDE to
override the PROTECTED state, IIRC.
Can you give an example
well, I fixed it with a shader. But, if this is meant to be protected, then
it shouldnt be overriden I think

Actually, PROTECTED keeps the state from being overridden.

Hi all -- I'm trying to find a way to set a Uniform to a different value

Hi,
- The boundingBox() method of the osg::DrawPixels is implemented, but a bit
wacky as it is based purely on pixel dimensions and will in general be
completely wrong. This throws off camera bounding box calculations badly. For
example a 200x200 pixel image is given a BB of 200x200x200 units

I forgot to mention that I am also calling releaseGLObjects on the

m_gw-close();
}
