A quick look at DAZ to see if anything important changed. Changes since DAZ Studio 4.20.1.17…
* support for the new iRay “curves/fibers for strand-based hair/fur” (and later fixes)
* iRay at “2021.1.2”
So it looks like if you want the latest “furry” iRay, you want DAZ 4.20.1.34.
Though if you go later than that and on into the public betas, at 4.20.1.58 you get…
* iRay at “2021.1.6”
* and a thorough overhaul of FBX export.
Looking at the iRay dev blog…
1.6 – was a “minor critical” bugfix.
1.5 – no mention.
1.4 – no mention.
1.3 – was “a minor bugfix”
The iRay devs are working toward a major iRay “2022.0.0” beta, which seems due soonish.
So unless you want to experiment with iRay hair, or think “minor critical” is worth the change, there doesn’t seem a great deal of need to upgrade DAZ just yet.
