[osg-users] Disable Backface Culling of a node
Hi there is there a way to disable the backface culling of a node? If we enable some transparency in a box, we want to see the back face. Will there be a problem, if we use lighting, does the back face be visible with the material color? Thanks a lot and regards Dominic ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Glenn thanks but this didn't work. We applied the mode on a loaded osg file. Is this a problem?

Hi Dominic, node-getOrCreateStateSet()-setMode( GL_CULL_FACE, osg::StateAttribute::OFF ); thanks but this didn't work. We applied the mode on a loaded osg file. Is this a problem? If the osg file contains a stateset which sets GL_CULL_FACE to ON below the root node where you set it to OFF, it will be overridden and will be ON for the drawables (state is inherited down into the leaf nodes). If you want to force GL_CULL_FACE to OFF for all nodes below the root of your .osg file, use osg::StateAttribute::OFF|osg::StateAttribute::OVERRIDE.
