Thanks for your reply Jason, I actually worked this out I think, I removed mat->setDiffuse and added
mat->setColorMode(osg::Material::ColorMode::DIFFUSE) and it seemed to do the trick! Not sure why, but hey, it works. I now have a shared stateset with various attributes like specular/backface culling etc... and vertex colors on the objects themselves :) On Fri, Jul 17, 2009 at 6:50 PM, Jason Daly <[email protected]> wrote: > > > Hi, Andrew, > > > Andrew Burnett-Thompson wrote: > >> // Set specular attribute >> mat->setDiffuse(osg::Material::Face::FRONT_AND_BACK, osg::Vec4(0,0,0,0)); >> mat->setSpecular(osg::Material::FRONT, osg::Vec4f(1.0f, 1.0f, 1.0f, >> 1.0f)); >> mat->setShininess(osg::Material::FRONT, 12.0f); >> mat->setColorMode(osg::Material::ColorMode::SPECULAR); >> sharedState->setAttribute(mat.get(), osg::StateAttribute::Values::ON); >> sharedState->setMode(GL_COLOR_MATERIAL, osg::StateAttribute::ON); >> /////////////////////// >> >> Of course, the material then mixes its color with the vertex color, >> despite the fact that its transparent. >> > > Try adding this to your global StateSet: > > osg::LightModel *lm =new osg::LightModel(); > lm->setColorControl(osg::LightModel::SEPARATE_SPECULAR_COLOR); > stateset->setAttributeAndModes(lm, osg::StateAttribute::ON); > > > I'm not sure if it'll work, but it's all I can think of... > > > --"J" > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >
