strange Shader´s reflection behaving

[^Lele^]

in Maya it is possible to drag and drop script snippets directly to Buttons. How should I do doing in Max so?

The same way as in maya.
For convenience, maybe make yourself a toolbar first, so you know it's editable.

oh yes really... thanks! =)
I tried it once or twice and it never worked. But that was also a long time ago.
