The ability to quickly take in Unity prefabs (models OR positions) into Houdini (as Geometry/Materials or as Points/Attributes) would be especially handy with Houdini –

In my use-case, I would like to be able to simply position these in a 64-bit world-space representation in Houdini, and use them to contribute to, say, volumetric/material data – then translate these back to Unity into some “local” space representation (i.e. a particular grid cell in an open world, for example).
