Hi Wojtek,
Ok, now I think I understand - I will submit fix for this case or if You
prefer you may do it. Basically we would want to add setter and getter
for the flag which will turn off render bin override, right ?
Hmmm... I added an osg::AlphaFunc with comparison GL_GREATER 0.0 to the
root of my scene graph, and it works well. So if this is the expected
behavior, perhaps the ShadowedScene could have this osg::AlphaFunc by
default?
shadowedScene->getOrCreateStateSet()->setAttributeAndModes(
new osg::AlphaFunc(osg::AlphaFunc::GREATER, 0.0),
osg::StateAttribute::ON);
Just hypothetically, for the same end result, what would be faster:
A) overriding the renderbins and using an AlphaFunc
B) disabling the override on the renderbin
(I suspect A, but I'm not that familiar with AlphaFunc)
I think it's expected that objects with textures which have texels at
alpha=0.0 will have holes in their shadows. So we should either document
this clearly, or set it by default, as it wasn't at all obvious to me,
at least.
Thanks,
J-S
