Will need some time to build that node tree because those functions are indeed very useful. (or will be once I know which bit does what)

Have found that with a lot of Blender Tutorials, there is a trend to do a youtube "Look at how fast I can do XYZ with sprinkles on" which no sane human can follow without
getting a mental stress fracture.

Interested in the dome you mentioned. Is that to be found in the Poser12 Content or can you turn the background into a dome? I mean, if I use EZDome, it also doesn't display in the preview either so..

On the whole, I am taking to Poser 12 despite the fact that it is time consuming to get to grips with Superfly. I was relatively adept with Firefly and its Daz equivalent 3Delight and have seen a lot of Physically Based Renders using Iray that were extremely underwhelming in comparison. Might be just my impression but in a lot of cases, the pictures had really boring lighting and complete absence of effects.
Since my preference is for Fantasy and Sci-Fi type stuff, I do have a love of light and effects. Think there used to be a product (discontinued) for Tenebroso Lighting for Daz, which would have been right up my street. Equally, I love volumetrics and so far, Superfly still feels a bit sterile in comparison but that will change I expect.

But Poser 12 has certainly gained my interest, even though most of the scenes and products made for Superfly seemed to be targeted at the IKEA Catalogue side of 3D Art, whereas my element is more in the realms of Prae's Hairs and things that remind me of indipendent music and UK Rpg scene of the 1980s.
