Hello here are my results the render which took over 20 hours to do a 2000 x 2000 and something HDRI and masses of reflections on poser firefly render.

1st attempt 2000 x 1500( I think ) = 23 seconds!

Problem there were no reflections! however the poser figure & Scenery looked excellent quality with noticeably much better shadows.

then.... I discovered how to turn on reflections!

2nd attempt 2000 x 1500 = 56 seconds Looked stunning just like the poser render I have not yet seen complete! (My missus complained at this point that I had not found this renderer in the first place rather than waste my time with firefly leaving computer on all day)

3rd Attempt 6500x5000 (I think) 300 ppi Added some cool lighting changed some textures to make them more realistic, upped  the reflections to insane levels added some seriously cool bump mapping decided to put some water in the scene (sloshing around my poser characters ankles and various objects on floor).

Then I rendered ..... and Vue Crashed!

Tryed again and turned down a few of the insane settings (I had completly maxed it out!)

56 minutes later Vue churned out a render still at 6500 x 5000 with stunning bump maps, reflectivity that I never thought possible (I have never achieved this detail from poser) The lighting looked 100 times better than poser Pro. ( I am not sure where HDRI option was in vue, but managed to find displacement maps, it looked infanitly better)

By this point my jaw was hanging open, realising how much more I could achieve with my time!

Also about a month ago I printed out an A3 poser pic I thought looked stunning I decided to do it on vue same dimensions but upped what I could reflections etc.

It was 3500 x 4900 ish ?

Upped the PPI to 600.

Bearing in mind this render took me 15 hours and I was pleased with it.

................. 1 minute and 58 seconds later.....

Stunning is all I can say it bettered the poser render in every way possible and the firefly render was almost laughable in comparison.

I have not tried hair as yet, but everything else I seemed to have tried looks amazing... I hope this helps.

I am now a Vue renderer !

Oh and I liked that idea of reposing in poser and it converting it to vue..  the vue interface is a bit more clunky than the one in poser (maybe its just me trying to learn it though.
