I took a quick look at this.

It seems that there actually was a Scatter node in P8 / PP2010 but it wasn't documented. A dir() of the poser Python object reveals a poser.kNodeTypeCodeSCATTER node.

While the node wasn't made available in the UI it looks as though the coincidental node name has caused it to be created when applying BB's shader.

My guess is that this was an abortive attempt at SSS which was dropped when SM realised a more radical approach was needed.

The node does actually work, in the sense that it contributes to the render. The results, though, are what you'd expect from something unfinished and undocumented ... nonsense.

Does make you wonder what else is lurking undocumented in the code :-)
