Hello,
I'm a developer on then french EL project and we meet the same problem. I succeeded in using the "glMaterialfv" command when I enabled GL_LIGHTING. Look at this :
{
glMaterialfv(GL_FRONT, GL_EMISSION, object_id->color );
}
else
{
glMaterialfv(GL_FRONT, GL_EMISSION, zero );
}
glEnable(GL_LIGHTING);
However, when I'm enabling that code, the "NEW_SELECTION" option can't be used
I also tried to use glDisable(GL_LIGHTING); on line 277... But if "NEW_SELECTION" is enabled, I'm able to see a lot of object but I'm unable to use those objets (I see the boat flags but I can't use them as teleporters)
