Personally I think it’s a no brainer. I know it’s like I’m asking to treat meshes as NURBS, but it’s not really is it I feel. Basically we have this hybrid geometry which, in simple cases (all quad and 1d / 2d arrays of faces), can be described as a surface underneath, but then manipulated in the free manner that SubD offers.
At the end of the day, it’s important to maintain synergy between the tools so that we’re not going down the line of ‘Tool A get’s you to Point A; get out of your car and into Tool B, and that’ll get you to Point B’. I’d be interested to know what the biggest limitation is. Are there not conditionals to determine whether a selection of quad faces form something which can be described as a surface for use with UDT bits? basically, how can we reuse great nurbs stuff and apply it to SubD logic.
I’d more than happily try and break something like this.
