World space coordinate inside a procedural

[hollierthomas]

Is it possible to refer to the world space root coordinate system inside a procedural? I have a ton a buildings laid out in a city which are each copies from a small set of procedurals. I would like to introduce some blotchy variation across the whole city by applying world space noise to the whole thing.

Sure.
Initiate the Noise P slot with a state vector P

Thanks!

Using maya, I also found out that the matrix output by the place3dTexture node stays locked to the scene's world origin rather than the procedural's transform node.

So, two ways to achieve this.
