My main problem is that I do not have *help file*! I walk thrue Maya like a totaly blindman. I use Maya4.0. I am sure that if I have *help file* all things should be easier to me. I just want to try 3D software- how it works, how to eat this... I swich from Adobe(photoshop, illustrator) and now all things changes! ("Can u imagine"... that CTRL+C, CTRL+V... do not work!) Edit>ungroup wont help. I think that Dragonfx understand my problem- I think that is shaders problem. When I create some 'primitives'- all have the same initialShadingGroup. In Command feedback; Maya wrote: "Error: Can't rename a readonly node" How can I turn off in duplicate copying the instances?... Once again-thank you for any help.
