I'm seeing some marked changes in the rendering in SR3, possibly connected with ambient occlusion, maybe? The most obvious effect I've seen where a water surface intersects a skin surface which has had a shader added using this Unimesh Realism Kit.

That's worked. Thanks. :)

If discussion over in the DAZ forums is anything to go by then the Mac version seems to have picked up a few new bugs (in particular, one fairly hideous one affecting some injected morphs) which might well make the new version somewhat less than usable on Macs...

...so, if you're using D|S on a Mac, think carefully before upgrading.
