Re: generator ops, self installing plugins

["Reinhard Claus" <rclaus(at)gmail.com>]

Hm that would mean there's no chance with the current SDK to write an op that changes topology (a la split edge/inset/extrude polys). At least unless there's something like a transient freeze for ops that affects only the current evaluation. Then geo could be read, stored, stored geo be changed, old geo temporarily frozen and then overwritten.

Generator ops the docs state pretty clearly that the seed mesh needs to be frozen if the op is generating geometry and this works only if the mesh is frozen prior to applying the op, otherwise it crashes. Same has been true of other ops of this type I've created. It kind of makes sense; your op is creating geometry from scratch then there's no point in any of the construction stack prior to that op.

 

Incorrectly connected? Not sure I understand.

 You dont need to freeze the geometry if youare using a scop, only if you are creating your geometry on script
I have seen polymesh generators die on me if the poly index array is incorrectly connected.

Got it. Freeze the seed object first.
