I'm not familiar with Indigo . . .
My area of expertise is more MEL now. I use to do C++, Visual Basic and assembly programming, but I guess MEL spoiled me rotten. After that Walkerman project, which was a really ambitious endeavor, I am wanting to get back into the visual part of animating for a while. . .
The Maya library and the web for that matter does not seem to have much info on that "objectType" command. I am not sure if I have even ever used it in any of my programming.
