Hi,
I think the problem maybe located in my custom Drawable class. It draws text
geometry instead of textured quads (like in osgText::Test). It basicaly works
like Group with multiple transforms and geodes with character geometry. But I
really need it to be Drawable (structure of transform will be memory consuming
and I can attach it to Geode in the same way as I attach regular osgText::Text).
How it works:
My custom Drawable calls draw method of every character geometry in it, some
characters have program in their stateset so I have to call
state.apply(character_goemetry.getStateSet()); and that's where it crashes. Is
it legal to call state.apply in drawImplementation method ?
It crashes while drawing my custom Drawable in function drawImplementation()
while rendering its content like this:
Code:
// for each glyph in CustomTextDrawable
for (int i = 0; i < itr->glyph->getNumDrawables(); ++i)
{
osg::Drawable* drawable = itr->glyph->getDrawable(i);
state.apply(drawable->getStateSet());
itr->glyph->getDrawable(i)->draw(renderInfo);
}

Btw. I didn't noticed this behavior in SingleThreaded Mode and it crashes only
when I'm copying subgraph (I'm also deep copying statesets in drawables, when
they need to change attribute values) and I do it once, then attach it to scene
and then destroy it afterwards.
Any ideas ?
Thank you!
Cheers,
Filip
