Hey man...it's fine by me...you are one of the best and are most generous with your models. You texture above average in Bryce and answer queries...I see no reason to not continue status quo myself. The answer would be "Because they are rendered in Bryce" IMO...jebus with DAZ content now available within Bryce it's pretty much an open field and as it looks to me, like development wise, as Bryce is dead in the water some stuff can be more easily built in other softwares so it is only logical to use the best tool available to get the best result..It ain't the hammer[tool] it's the carpenter[artist].. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
