I'm glad to see this subforum exists. As an XSI user from way back a little part of me died inside when Autodesk took over and booleaned Softimage into the ground. I'm completely new to Houdini and like what I see in the upcoming Houdini 16 release which has some resemblance to XSI. Hope to see this forum get utilized by former XSI'ers.

Hi,
and Welcome! The sub-form is used by former/current (there aren't really any former XSI users as of yet) so your hope is become reality.
Most “purebred” Houdini users are at least just as friendly and eager to help, so feel free to post in any sub-forum you want. I imagine you already know this, so I guess I'm just succumbing to an irrational urge to state the obvious.
