HI Brad, On your custom drawable just do:
drawable->getOrCreateStateSet()->setTextureMode(0,GL_TEXTURED_2D, osg::StateAttribute::ON); Or drawable->getOrCreateStateSet()->setTextureMode(0,GL_TEXTURED_2D, osg::StateAttribute::ON | osg::StateAttribute::PROTECTED); The later protecting any settings from being overridden from StateSet inherited from above.

Hi, I have an osg::Drawable with a drawImplementation that uses texture unit zero. I have tried using the code below on the stateset of my drawable to disable all other texture units. Unexpectedly I find the texture unit which is enabled to be the last one I disabled with stateset->setTextureMode(). Is there anyway to set up the stateset so texture unit 0 is guaranteed to be the active texture unit when my draw implementation gets called, or is there something I am missing?
