Okay, so I see Vray for Cinema4d seems to use a more linearly structured system, with a layer-based UI metaphor?

Underneath that, well... not sure its reasonable to compare Firefly with VRay? The price differential alone kind of precludes that surely?

However in terms of the material configuration in Poser, on the whole I'm quite happy with Poser's nodes based system... and frankly, if Bagginsbill is happy working with it... that's even better for me ;-)

If I need a more linearly structured way of configuring the Poser material nodes, well, there's the facility to write an intermediate UI layer... e.g. as Snarlygribbly has done with EZSkin?

Should SM do this themselves in due course... perhaps... but as an end user I'm not too fussed who does it. In a lot of ways, for me personally at least, having Python based add-ons for this sort of thing, made in an open way by the likes of Snarlygribbly, is better... because if I'm not entirely happy with how they work, I can always change them.

Just my opinion on this...

...and I'm not saying, if I was working at a level where Cinema4d and Vray was in my budget, that I wouldn't be equally happy with that system ;-)
