Hi Thomas,
here it was the "easy way" to get a fitting tl_map - photoshop...

Of course I tried other ways to "automate" it, but The real cause of not further
investigating it further was - it was slow.
In the end I used a partial render of the big oak at the middle left, because
render speed was only a fifth.

The real use of the fake is for more intimate scenes with single usage - at
least until we get a real implementation of translucency maps and all the other
types of texture maps swirling around DAZ studio - roughness, normal, ao-maps
and so on...


......
Personally I don't fear corona anymore, because my family had an obsure severe
illness back in march/april - and I never was a hypochondriac. I'll invest in
antibody tests, when they are available at a reasonable price.

Norbert

and Keep corona-free!
