You can usually use a nodemask to perform this trick. You may wish to clone the original entity, set the line width wider, and draw that clone, so you don't disrupt the state of the original. Set your Z-buffer depth test to GL_LEQUAL so that re-drawing the same part actually draws it again, over top of the copy already represented in the Z-buffer. -- Chris 'Xenon' Hanson, omo sanza lettere.
