Hi David, Tom,
Are you enabling transparency? - for example by:
Code:
osg::StateSet* state = node->getOrCreateStateSet();
state->setRenderingHint( osg::StateSet::TRANSPARENT_BIN );
state->setMode( GL_DEPTH_TEST, osg::StateAttribute::ON );
That last one should probably have been:
state->setMode( GL_BLEND, osg::StateAttribute::ON );
GL_DEPTH_TEST is enabled by default, but blending is not. So that will
be why transparent things are showing up opaque. The transparent bin
setting is just so the transparent objects are rendered in the right
order (after opaque objects, and in back-to-front order), and wouldn't
prevent things from looking transparent, they just wouldn't be rendered
correctly in some situations.
So for transparency you need to enable GL_BLEND, and for correct
transparency you need to set the rendering hint to TRANSPARENT_BIN (or
setRenderbinDetails( n, "DepthSortedBin" ); where n is the bin you want,
if you want to explicitly order some transparent objects to be rendered
before/after others).
Hope this helps,
J-S
