Thanks for reply

I have Reality since beginning (version1) but didn't use so much because until recently i didn't use so much DazStudio

Now i surprise me to use DAZSTudio 4,5 more and more often

And i want to use Reality 2,5 more often too

But i don't like the noise Ok i see an option in Luxrender for reucing noise but it reduce detail too much Anyway i can reduce noise in post production with Topaz plugin

But i have some render when version 2 was bought with nice looking render without too much noise and i don't remember what i did for it

 

And one other thing

I see and try to follow the tube with the links you put on the message ;i don't know why but with softbox i can select the snoot but i cannot do nothing with it (yscale don't work,for example) I know that the version of DAZ Studio used in video is older but i cannot see where are the snoot proprieties we see  in the video (not in parameters,not in posing ,neither in shape)
