Thank you, Primorge.

FWIW, I used one of the bundled 'wigs' for LaF that looks okay but did not significantly slow editing.

Also, just do lighting 'with wig' test renders of head+shoulders to mitigate weary wait...

Another 'gotcha' is complex foliage such as a common-or-garden lawn: 35 MB OBJ ??? I wrangled that monster by using Poser's ground plane and OBJ's bump-map set to 'displacement'. Just mind you set appropriate displacement scaling there, and  'displacement bounds' in figure properties. With care you can get 'Elephant Grass'...
