Hi,
To use a mutipass I need to turn on blending. (at least with open gl)
Is it also needed with osgFX or is it automatic?
I tried adding a BlendEquation object to my stateset, but I could not figure
out which symbolic constant corresponds to the gl functions
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
blendFunc = new osg::BlendFunc();
blendFunc->setFunction(osg::BlendFunc::SRC_ALPHA,
osg::BlendFunc::ONE_MINUS_SRC_ALPHA);
stateSet->setMode(GL_BLEND, osg::StateAttribute::ON);
stateSet->setAttributeAndModes(blendFunc, osg::StateAttribute::ON);
--"J"
