Re: Native XSI LSCM Unwrapping

Ok, I understand now! Too bad...

Hi Ahmidou,

The problem isn't adding another cluster as an input port, it's the
way XSI evaluates doesn't allow for restructuring just part of the UV
set and having modifications to the other part applied below the
operator. So there's no way to really develop an interactive tool like
would be ideal for this.

An option might be having two operators - one which creates the
initial UV set and a partner one which lives in the animation stack.
This way you move the pinned points in the modeling stack and XSI
shifts it all again in the animation stack - this may provide a way of
getting interactive modification of the UV set using pins.

Anyone at Soft have an idea on this?

Cheers,

Alan.
