lighting and on-the-fly objects

[renama]

This thread is discussing the exact issue we need in our project. But after many tries, I still could not make the 3D effect on the on-the-fly objects. The cylinder and cone do not have the same lighting effect with the imported 3D ball. I changed the value of obj.shininess, obj.emissive,obj.specular, and etc. but it does not work. I believe Vizard does support this function, I just could not figure out how to make it happen. Can anybody help. I apprecate it....
